People call me the laundry angel but it's all a lie.
I don't understand. Why do you think you're referred to as the laundry angel?
I tend to know when people need help with laundry and I always offer to do it for them. Really I'm just trying to get brownie points.
I'm sure everyone appreciates your help but helping just so they owe you something is wrong. If people knew you did that they would just avoid you altogether or just never ask you for anything even when they actually do need help.
I don't care what they really think, I'm closer to being a hero than these losers.
You might be exaggerating, doing laundry does not make you a hero. And people don't owe you anything for you doing them a favor. Either do it to be nice or don't do it at all.
