I'm not going to let a kid in my class use my charger
Why won't you let him use your charger?
It's my charger, and he's a bad boy who plays with other people's things.
It's mean to not share with others. You should help lend the kid things if he needs it.
I don't give a fuck about this kid. We should do what we say not what we do.
It's still nicer to lend people things if they need them. How would you feel if you needed something and your classmates wouldn't share with you?
