I was having snacks with a friend the other day, i had pretzels and my friend was licking candy canes when he told me a weird story. He said that, the night before he was at a party at some rich guy's house, where he saw 24 faces at a table, some men , a few women, but apparently there were only 13 hearts at the table. After a while my friend said since i had pretzels he is going to pay up the bills. I was a little surprised, as he usually never pays. Now what did my friend see the night before and why did he pay?
