What are your "must have" items in your handbag?

I've seen women with some strange things in their purses. Heck, I've had some strange things in my purse. Standing at the checkout at the grocery store and pulling a pacifier or some fruit snacks out of my handbag screams "I'm a Mom, and I have random things in my purse to keep my kids occupied whenever necessary"!!! I try to clean out my bag every so often, but it never fails, things keep popping up in there that I forgot about, and every so often, that I have no idea how it got there. So, what are the things that you absolutely must have in your handbag at all times? Here's my list:
-wallet
-lipstick
-kleenex
-pen
-business cards
-keys
-sunglasses

Wow, its no wonder my handbag is huge. That doesn't even take into consideration the Cheerios.
