First off, I’m a Libertarian, glad to know I’m selfish. Anyway, parents work so hard. They have to take care of their child, especially a small one, constantly. Parents deserve to go out and eat when they want to. It’s not selfish, they just need to get out of the house, or maybe they just want to do something. You can’t help it if a baby cries, you can’t stop the baby, it’s no ones fault. I think you are selfish for judging parents because their baby is crying. If you don’t like it, leave.
