Oh, I feel for you! I know what it's like to have a purse and all its contents stolen. The scumbag who stole my purse five years ago was never caught. Luckily, I'd photocopied all of my cards, front and back, so that it was easy to get in touch with all of the companies. I check my credit report twice per year, and I have my Social Security report mailed to me annually just so that I can monitor things. Nothing with my SSN number on it was stolen because I don't keep that card in my wallet, thank goodness! Still, with all the identity theft going on, I like to keep tabs on my reports.
Another thing to watch out for, which I noticed the other day while buying groceries, is leaving one's purse in the cart. I never, never, never do that because thieves can be quick, and the fact that cameras are all over the place doesn't seem to deter them. It sure would suck to get to the checkout line only to find that my wallet is missing!
