Young children laughing. To me it the sound of pure joy. As people get older they often try to temper or force a laugh so they are not judged. With small children they laugh with full force and there is worries attached.

I guess it would have to be the sound of my Hound playing with his squeaker toys ! I can hear them anywhere in the house so I guess that means it's time to play! He has one that's really loud and he hasn't been able to wreck it ! LOL
