1) Very. If you don't respect each other, then there's no friendship in the first place. At the same time, respect has its limits too (I don't know, sometimes they don't deserve it anymore or you have to be disrespectful so you can make sure your friend doesn't do something stupid/you wake him-her up to reality so on).
2) I can't answer this one because I always contact people if something's wrong (or I'm always early). Not doing that is seriously rude xD but just to help you out, probably say sorry and then explain the situation and continue asking for forgiveness throughout the day. Tho I'm sure, even if the friends had been annoyed at first, they'll later forget about it.

1. Its like without it, we're not friends, and its like not human being. For friendship or not, we should respect one another.. :)
2. Id definitely say sorry, of course.. I just hope they arent that so mad, too mad they cant accept my apology :D

1. What is friendship without it? In friendships,respect is just something that comes along with it. If you don't have respect for one another, you probably shouldn't consider you guys as friends.
2. I'd probably apologize. I don't apologize too often so that tells my friends something so they wouldn't push on with it and understand. If I was that late, I probably had a damn good reason.

1. friendship need respect, we are all human being after all, who never want to be respected
2. one hour late but they still come right?? maybe there is reason to be late, but one hour is too much for waiting, no contact at all, and if they end up not coming, i will be angry of course, but you have to listen to their reason first and try to understand them

1) There definitely has to be respect.
2) If you are late then the question is why hasn't there been any calls or texts?

1) So vital. Without respect, there's no friendship.

2) This actually a hard question hmm. I will apologize and explain the reason why I'm late. Maybe my friend will understand me.
