When I was little, I had a cool wooden toy box that my Dad had built. Originally it was my brother’s, but as with all things I inherited it from him. Consequently, he did eventually end up with it again when he had kids…but I digress.
I used to dig my toys out of the toy box and hide inside it. Who knows why I did this, but it might have something to do with that other post about getting inside things. So, being inside the toy box with the lid closed is how I found out I was claustrophobic.
