Maybe it's because they're 20 (above) and almost 19 (below).
I suppose that's a good possibility. LOL!
Fortunately, at 9 years old, my niece still enjoys bubble blowing. She's pretty good at it, too.
POP!
This has always been one of her favorite things to do with me.
I sure could've used her the other day when I was trying to blow bubbles in the cold so they would freeze. It was a little challenging to blow them, set down the wet, drippy wand, get the camera up (after wiping my hand on my jeans), compose, focus, and get a shot before they popped. But I still got some.
Good times all the way around.
