Meet with X Girl friend

I am standing in line to deposit money in the bank, a good man behind me is looking at me with a demonic smile. I was a little hesitant to return to side He called me and said: I know why I am smiling?

Naturally I said, "How do I know, brother?"He again lifted the hand with the optional smile and said, "He does not see the Cash Counter's girl, he is my X Girlfriend"I said: "Then there was a problem, but you're looking happy?"He says: "My love was rejected by marriage, years ago, I heard that I have been employed in this field, and after that every month I have deposited my son's account with my wife's name"
