I have my house fairly full of objects and varied experiences and guess what? It has not drastically changed that much over 15 years but people can't see it all, can't remember it all, and often remark "Oh, look at that, that's "new" isn't it!"
"It was new ...10 years ago."
People also lose all track of time when going through my house and are very surprised that 90 minutes or more have passed since they walked in here.
I guess this means I have entertained or distracted them, given them some new things to think about or consider, basically engaged their minds with..something unusual. (And I have a whole lot of fun myself as it happens.)
After 20 years I have almost accumulated enough laugh-energy to power my return to my home planet, Laffingyerassoff!
Hey earth, it's been fun.
