Umm....yeah, I'm STILL like your son at age...
Right there with you OD at 51 LOL
The beach and the sandpit are still founts of almost endless entertainment. I say almost because I can still vividly remember the horror of my first cat cacky mining experience. Nothing, to this day, rivals its olfactory odiousness for me.
It doesn't stop there with mere sand either one of the things that I love about the Spring is the smell of the earth when digging garden beds. I have beds that I can sink my arms into up to the elbows and it is a glorious thing.
My DD appears to be cut from the same cloth thankfully :-)
