Why did you not pay for the card you said you would pay for? Do you sleep well at night, knowing that other people might have to go hungry because you stole their food right out of their kid's mouth?
Hopefully life will turn you into a better person that that, I would hate to see someone else take advantage of you like that and you ended up suffering because of it. You really should do the right thing and pay @thatsweeneyguy what you owe him.
No matter what kind of trouble you may have gotten yourself in, it's no excuse to steal from nice people. If you need help, all you have to do is ask. There are plenty of people who will do what they can, myself included.
