What do you think of me not going to class today?
That's is pretty irresponsible. Why won't you go to class?
I just don't feel like going there and talking to my classmates.
You shouldn't ditch your classes. It's wrong to not care about your education just because you don't like your classmates.
It's too boring to study and I think I can slack today. I'm just going to do something else
What if you miss something important? Even if you get the notes from someone you could miss out on asking questions and participating.
