Go outside
Yesterday evening I just needed to get the kids out of the house. They were whiny and so was I. It was one of those evenings where I wanted things to be a certain way and it wasn't and when things are like that I like to go into task mode and just have alone time, but when you have 3 little kids and a wife you can't just do that.
So I took them to an open field and we all just ran around outside for a while. Kicking soccer balls, throwing footballs, playing follow-the-leader, and tag. We needed to get outside to run off some energy. We all needed it. Sometimes all we need is just to get outside.
