Advice for the paranoid

Today's advice letter:

Dear Annie: Years ago, parents used to put up placards in their children's bedroom windows to let firemen know where they were in case of fire. That proved dangerous because pedophiles also knew which bedrooms the children were in.

Now parents are putting up stick figures of their families on the back of the car windows, including how many boys and girls they have.

Yesterday, I saw a car with two soccer ball emblems in the back window, each with the name of one of two girls. I assume those two girls were their daughters. To me, this is as dangerous as the window placards because any pedophile could follow the car home and target the children in the future. Should I be concerned for these children? — New York

Life must be difficult when your bizarre paranoid fears conflict. It seems to me that if a pedophile were going to follow a car, he would follow a car with kids and not a car with stick figures in the window. But then, I had no idea that pedophiles follow placards that were put in bedroom windows to guide firemen. The whole letter seems like a joke to me.
