We usually will not answer a number we do not recognize, but once in a while if I am waiting for a call back from a company they use cel phones that are not recognized so I will answer. Last week my phone rang and my DH asked me to answer so I did. It was a scammer, and it was the Soc. Security nonsense - so I said, "Yea I win!" The caller said what did you win? "My DH bet me $20.00 you wouldn't call back because I informed the guy last week that my DH works for the FBI and investigates scam calls you would never call me again, and hear you are and I have your number!" He hung up.
My mother and father used to say sometimes I could be a real smart alec - goes they were right.
