You have no choice but to text him.

"Hi. Are you busy? I want to discuss something. Maybe I will take about 20 minutes."

You wait for him to reply. After 20 minutes, you got a text from him.

"Ok."

"OMG. He just replied that to me? I really can't understand him. I do this homework by myself and he even don't help me to finish it. Such a brat. It's supposed to be a groupwork. Can't you understand that?!" you talked to yourself.

After 20 minutes of texting him, you want to discuss more but suddenly he send you a message.

"Enough for 20 minutes, so I got to go now. Bye"

"Wait, but we're not done yet. I've so many things to ask."

"What? It's not my fault. You said you just want to take my time about 20 minutes. So, we're done. It's already 20 minutes. Please remember this, after this just say that you want to take my time about 1 hour. I really don't like people who are not keep their word. If you say 20 minutes, then just 20 minutes. Understand? Bye."

You just stare blankly at your phone. You can't think wisely right now. You never imagine that he's really like a bitch. And you just make a decision to finish this homework by yourself and don't ever bother to ask him any question. Because end up, he just make you pissed off.

"What the hell--"
