Someone you went on one bad date with three years ago and who unfortunately still has your email address has added you as a friend on Facebook

I know it’s exciting and fun to use the email friend finder on Facebook – I know! I’ve done it a few times myself. A good 50-60% of the email addresses in the address book of the account I've been using for about five years belong to people I don’t actually know. People I’ve bought things from or sold things to on ebay or craigslist or amazon. People I've talked about subletting to or from. People I've gone on one bad date with and hoped to never hear from again after not returning their last call/text/email because of the crushing dullitude I'd suffered in their company . Why bad date guy? Why have you added me as a friend on Facebook? I couldn’t hit ignore fast enough.
