when you are somewhere and there is nowhere to put it? Like, I was at a restaurant recently, and there were no empty chairs at our table, and the back of the chair were rounded so I could not hang my purse on it. There was no room on the table. This is not a problem for me, as I have a crappy Target purse, but I was thinking about that as I have been looking at pricey purses lately. I kind of LIKE the freedom of not caring about my purse! Oh, and sometimes, in a public bathroom, I see the women in the stall next to me put their purse ON THE FLOOR! What is up with that? That is gross! I won't even do that with my Target purse, LOL!
