1. A tan.
Scold me if you want, but I am a woman in my 30's, and if I want a tan I'm getting one. Real, fake, sprayed, however. I don't want to bake myself to look like a Louis Vuitton, (mostly because if I did my neighbor would kidnap me - she's obsessed with LV), but I like to be able to wear shorts with less fear. (notice I said less fear, not no fear).
(I should also not that if you ever attempt to google "suntan images", there is a lot of nasty, and often unattractive, nudity. Yikes.)
2. The pool.
How many other activities can you come up with that all 3 kids will agree on?? (other than Chuck e Cheese - and tha's a BIG no). Pack a lunch and some towels - done.
The kids get worn out, and I get a healthy dose of my #1.
