To be a kid again

I sitting here at the local pool, watching my kids play and swim with other kids. They are having a blast. Kids build bridges fast and make friends even faster. Kids don't hold grudges and don't hold onto baggage. Why as adults do we lose this? When do we change and decide we can't move on from things. When does this happen?

Is it also hard for us adults to say sorry. We just plain suck at it. We teach our kids to own their mistakes and tell anybody that they are sorry for hurting them. Not us big kids, we dig our heals in and just hold onto the gabage that is crap. But how do you de clutter the crap that really has no meaning. 

I think I'm going to start taking pointers from my kids. I will have no baggage. I will hold no crap in and I will try to build bridges when there seems no way to. Im going to try and find that innocence while  still holding all the knowledge I have learnt in this life so far.
