I'm going to deny my friend rides home from work an hour before I get off
Why would you not want to take them?
Of course, I don't want to take him because he's such a pain in the ass.
If you have already agreed to help someone out it is wrong to back out. If you think he's a pain in the ass you should tell him why.
I don't have to listen to this retarded stuff, I'm deleting the entire chat.
I think that you should just do it anyways, since you already said you would. They are relying on you, you should not let them down.
