"Hello ladies, thanks for coming to my party! Let me take your coats. Now before you go in, I must apologise for the severe lack of guys that have turned up. In fact, there's only me and a couple of friends. I'm well aware that nobody likes a party with a ratio this bad and I feel terrible about it. I did try to invite an equal number of girls and guys and am even tempted to call the whole thing off, to be honest. Again, really sorry!"
