Since Auntie Flo no longer visits my house, girly things are passé, but currently in my zipper compartment is:
a ponytail holder for those hot flash moments, my DH's epi pen, a pen pen, a mini emery board, some loose change, $10, the last pair of earrings I wore and took off before I got home, a Tide pen, and 3 sticks of chewing gum.
I must confess I keep neither the receipts nor the cards.
