Mike = Sarcasm

If any of you know my husband, than you know how sarcastic he can be!  Here is the latest of his sarcasm: we were driving around looking for a Christmas tree and listening to the radio.  I saw a sign that said, "Friends are like snowflakes, >insert something about being unique and different" (I can't remember exactly what it said).  I read it out loud because I liked what it said.  And Mike being Mike, replied: "Friends are like snowflakes, cold and hard to shovel off of the driveway".  I laughed because it was funny and because I know he didn't really mean it.  He was just being his sarcastic self.
