I am not going to help a 12 or 13 year old who fell off his bike.
How did he fall off his bike?
He was being so careless about it.
It is normal for kids to be careless. You should help a child. If you do not you will look like a coward.
I am not a coward, I just have higher priorities than helping a bum.
This kid is not a bum and you should help him up. He may have injured himself.
