Hey look. This is my decision now. I'm not going to pay for my friend's concert ticket and ditch him.
Are you just saying that or is it for real? Why would you ditch him and not pay?
He is so cheap when it comes to paying for stuff, I fully deserve the ticket.
You really should help out your friend. It's wrong to abandon your friends. That's selfish and rude.
I try to look after myself.
Ditching your friend at this time seems foolish, why would you want to loose a friend. I think you need to be more generous and he should also be of help to your when you need it. Just have a rule in place that you both tale turns paying.
