Apparently VD day is one busy day for private detectives. Interesting.

According to the Associated Press, detectives are hired mainly by spouses to see if their mate is secretly having an affair.  One undercover agent who wishes to remain anonymous (you think?), says he busts more husbands and wives every year cheating on Valentine's Day. How romantic.

One tip, is to check the credit card bill after Valentine's Day for any strange charges.

I guess one good sign of cheating is if your significant other does NOT want to spend Valentine's Day with you period.  Possible red flag!  I don't think you need a private eye to figure that out.

So the moral of this story is Valentine's Day is not only for lovers, it is for cheaters too.
