Thus far there's very little fighting in my house. Both kids bicker a little here and there, but that's about the extent of it. In thinking about it though, I like the way little little kids fight. They yell, they sometimes hit, they cry, they lay it all out. The have their fight, they feel their emotions and then they move on with life. I remember when I was growing up that the worst insult my friends and I would fling at each other was "You can't come to my birthday party!"
As an adult, the fighting I see around me is much more disturbing. Fortunately, there isn't much of it, but it's much more a war of words, agenda's and subtle insults that a 3 year old doesn't even understand. There's generally not yelling, hitting, or raw emotion spewed all over the place. Sometimes crying, sometimes absolute disrespect, sometimes just junk. It's not all laid out there, dealt with and then over. It lingers, the relationships change and often, things are never the same.
Maybe we should institute a "fight like a toddler day". A day to just lay it all out, deal with it, and then make up and play together.
