be more responsible - can you??

Today, I was very aggrieved with someone. Someone who I thought is a very caliber, responsible, and trusted person. But he has change my nice view about him when he failed to complete the task given to him.

Yes, I know he got so many works, assignments, projects, tests and quizzes. But he can't give any excuse lorr because I'm also a student  like him. What is more surprising is, we are in the same class/lecture. That's mean we got the same things to do. It's crazy to say that he got busy than me, am I right??

I can let it go if it's a difficult one. But I gave him the simplest one laa. How can he can't complete it??

Sorry to say, I'm really disappointed with you bro....
