Accept the fact that life doesn't always (actually, never) goes as planned or is easy. Them think about how much your life works suck of all the people who angered you today were not in your life (you have to think past the initial "I can do whatever I want" phase and into the "I'm an adult whose only purpose in life is to survive because of instinct").

Then hug those kids before bed, tell them you love them, ask them if tomorrow they well try to do better if you promise to do the same (whatever the did, this is generic).

When your wife comes home, greet her with a clean kitchen and a glass of water with cucumber in it or something, tell her the kids settled down and you got to relax for a bit, and ask her how things went.
