What is the difference between visual coding, semantic coding and acoustic coding? What the is semantic coding? I was startled away from my homework by my phone buzzing beside me. I looked over and was surprised to see Chaeyoung's name flashing on the screen.   "Hello?" I answered, confused.   "Hey, Y/N. Do you want to grab some coffee or something?"   "Um... You do realise it's like ten in the evening right?"   "Sorry, are you busy?" Chaeyoung asked as if the thought had never occurred to her.   "Mmhmm, just finishing my psych homework," I sleepily responded.   "Oh, sorry…" Chaeyoung sounded disappointed and something else that I couldn't pinpoint but I didn't like.   It made me wake up a little more. "It's alright. Where do you want to meet?"   "It's alright, don't…"   "Where?" I interrupted.   "Starbucks is still open," Chaeyoung answered, quickly.   "Meet you there in twenty minutes," I replied, saying bye and hanging up the phone.   Quickly putting on my jacket, I grabbed my keys and headed out the door. When I walked up to Starbucks, I promptly spotted Chaeyoung's car. Seeing the blonde sitting at a table, I went inside, ordered a coffee, needing the caffeine and then strolled over to her.   Behind the masked smile, she wore on her face, there was a sorrowful sadness. She anxiously looked at her left and right, repeatedly as a single sound passed by, presumably checking for any signs of my appearance. I don't blame her for being anxious. I had overreacted last night and somewhat taken my anger out on her. I could see how remorseful she looked, sitting there stirring her coffee and to be honest, it made me feel even worse.   "Hey, Chipmunk. What's up?" I asked the Australian girl, getting her attention.   "Hey," Chaeyoung replied, looking up from her drink.   "How are you?" I asked, still really confused why I was here. I knew we hadn't left things on the best note last night but I didn't think she'd want to talk about it this soon. Especially not at ten o'clock in the evening.   Chaeyoung let out a sarcastic laugh before saying, "I've been better but forget about me. How are you?"   I shrugged, "Fine I guess."   "Have you spoken to Lisa yet?"   "Why would I?"   Chaeyoung shrugged, "I thought you'd want to talk it out."   Why the hell would I want to talk to Lisa about her ing someone else? I don't even want to see her let alone talk to her.   "Are you alright? You spaced out for a moment," The concern was thick in her voice.   "Do you care?" I shot back.   Chaeyoung was taken back by the anger in my voice. "Of course I do. I called you because I wanted to see if you were ok. I didn't mean to hurt you by not telling you about Lisa. I just wanted to shield you from getting hurt."   I sighed, deflating in front of Chaeyoung's eyes. "I'm sorry, I shouldn't have said that. I know you were only trying to prevent me from getting hurt by not telling me. I was just annoyed because I thought you of all people would tell me."   The blonde girl's face seemed to light up at my confession. "I should be the one apologising, Y/N."   "It's fine," I stated. "Did you finish Mr Chan's psychology homework?"   "Of course."   "Why am I not surprised?" I asked her with a teasing smile. "Anyway, that's good because I didn't and I'm gonna need your help."   Chaeyoung's mouth dropped in a mocking expression of shock. "Is that all you want me for?"   "I mean,
