Two men talk:
-Take a cigarette, offers one.
-I don’t smoke. I’ve tried it once, but I didn’t like it.
-How about drinks?
-I had a drink once and I don’t want any more.
-Hey, let’s play cards!
-No, man, once I’ve played cards and it was the first and the last time. There is my son, he will play with you.
-I bet he is your only son too!
