I often tell my kids that we don't do "fair" in our house. My boys know that when one brother goes to a birthday party and they are left behind, that it's an opportunity to be happy for them. And just because one brother got an ice cream cone while out on errands with dad, that doesn't mean that they will get one too. Honestly, if we did "fair" everyone would be doing a lot MORE chores and have a lot less "treats."
