Can't say this enough
Seriously, I think it's physically impossible to be pissed off or angry or what have you if you're coloring pictures or making things with play dough. It's just impossible. It's all free-form and no rules are applied and it's a diversion from adult life in the same way that it's a source of incredible joy and pride in accomplishment for kids. They also tend to focus on it if it's fun for them and hopefully reduce your stress level.
Just this morning I was coloring with my 2.5 year old. I enjoyed it so much that I barely noticed when he was through and went off with a cousin as I happily kept coloring my picture without thinking about the extended family discussing the restaurant and meal and drinks and fun they had the night before.
Little things for little people. Think like them. Love them and yourself and realize that you can't do those things effectively if you're drunk. I'm trying to learn and take it all in myself.
