B: Tom, aren’t you a little too old to be trick-or - treating?

A: What are you talking about?  Where is your Halloween spirit ? Didn’t you ever dress up in a costume and go around the neighborhood trick-or-treating with your friends?

B: Of course， I did, but when I was ten!  Trick -or-treating is for kids, plus, I ’m sure people will think you’re a kidnapper or something, running around with kids NCP at night.

A: Whatever, I’m going next door I heard Mrs. Robinson is giving out big bags of M&Ms!
