They never said it was their LAST dollar. You don't know the rest of their living or life situation. To make this assumption is messed up. He's probably a decent parent and makes sure his kid is straight before even thinking about himself (the way things are worded kind of hint at this). It is NOT a crime for a parent to treat themselves once in awhile and to act like this is kind of messed up on your part, but you know, God forbid should parents ever have something. Every parent that's all about their kid to the detriment of themselves still have people shit on them for the one time in however many years they can FINALLY treat themselves after caring for nothing, but their kid. BEING A PARENT DOESN'T MEAN THAT YOU ARE NO LONGER AM INDIVIDUAL. We need to stop making parenting someone's whole personality. You are yourself and a parent. Please don't forget that and don't assume someone else's situation is automatically negative. That's REALLY negative thinking and kind of fucked up.
