Never tell someone not to be sad because others have it worse. It's like telling them not to be happy because others have it better.

Avoid complaining. This one's pretty hard but it'll work just fine if you practice it because your mind is set that you can do it and survive. Especially, don't complain about something that is practically a blessing. Don't act like a spoiled immature adult, or if you're a kid, that's not an excuse to be one.

Avoid focusing on someone's flaws. Instead, focus on the good things they do. I hate it when kind people beat themselves up just because some insensitive people are guilt-tripping them when they make a mistakes. Never let a single mistake cover up all the good deeds that a person has done to you or to others.

Avoid talking about someone who's practically just right beside you or somewhere near you. It's not just an act of disrespect, but it's also mean. Well, basically, just stop yourself from talking about someone behind their backs really. Let me give you a scenario that counts. For example, a female student passes by and rumours have been spreading about her so you ask your friend after she walked past you if the rumor about her was true. That's a bit mean and you'll look a bit too eager for gossip. It doesn't look polite, really.

Everybody probably knows this quote but please, don't judge a book by its cover. Sure, she smokes, she drinks alcohol, she has an inappropriate ual sense of humor but so what? If she has the characteristics of a person who truly cares about a friend, a family, or even a stranger, then you have no right to accuse her of being some heartless jerk. You can't just conclude that a person isn't nice just because he drinks or smokes or anything like that.

Do not be a hypocrite. You can't tell someone to stop backstabbing people if you actually do so. That's not just mean, but it's a bit stupid don't you think?

Never make a completely innocent person look bad. Probably by blaming him or using him as a scapegoat or just to trash his image. Never do that. For example, you start ignoring this guy. This guy starts running after you, looking like an idiot. So one day, this guy gives up and moves on with his life, choosing to ignore you just because you told him to stay away and stop talking to you. Then you tell everyone that you're sad because he's ignoring you and that he left you? That's bull, man.

Also, please. Please do not use money or any materialistic things as a reason to become friends with someone. Friendship is more than free food and free luxuries-- it's all about the deep talks, the stupid and dumb conversations, the fights that end a minute later, things like that. Do not go like "oh, you won't buy me this ring/sushi/kimchi/shoes/car/house or this damn tree? well, fine. our friendship is over.". That's just immature and mean.

Look at things from other perspectives. Try to put yourself in their place too. Respect other people's decisions. If they don't want to eat in that place? Then talk it out. Don't go like, "well fiiiine, eat there. leave me here, you always do that." well daaaamn, no one wanted to leave you so just--

Don't act like a boss. Not everything you want comes first. Do not get mad if your boyfriend is a vegetarian and you hate salads. That's so insensitive. If your friend hangs out with other people, let them be. If the order comes a bit late, do not be mean to the staffs. That's so childish.

This one's a bit connected to the second one. Please don't complain for something you didn't even work your off for. Don't curse a teacher for giving you a bad grade if you didn't really study. That's just..dumb. If you don't want something bad to happen, then do something about it!

Don't question someone's passion or interest. Don't go like, "really? you like watching cooking shows? god, that's so boring! ew.". You're just gonna sound like a douchebag. Really. Same goes to people who are like, "are you seriously going to spend money for that piece of crap?" If he has the money to do so and if he really wants to, then let him be! It's his own choice. It's what makes him happy.

CONSIDER OTHER PEOPLE'S FEELINGS TOO. DON'T BE A SELFISH, IMPOLITE, DISRESPECTFUL, SPOILED, BRATTY, MEAN, etc. DOUCHEBAG.

Also, keep in mind that depression is not a contest. Damn, you're sad, I'm sad, we're all sad, period! Everyone is fighing a battle you know nothing about so shut it. Just be there for each other instead.

So yeah. I'd probably make a second version of this since some people around me are really stressing me out. Sometimes, I feel like I make the wrong choice of friends but I just...I can't leave them. I'm somehow attached to them. They're good friends but sometimes, when problems arises, they just.. I don't know. Get out of reach? It really pains me everytime. 

If you want to add more don'ts, feel free to tell me about it right below at the comments section or if you want to talk privately, I'm free.
