No, I don't think your worries are something to laugh at. I'm kind-of leaning toward the idea that worries like ours come from living in a world in which violence, crime, and harm is somewhat common-place. I think women are especially sensitive to it. My husband (we've been married for 30+ years, but no longer live together) never locks his door when he drives. I keep telling him that he could be car-jacked, that he should lock his door. He doesn't seem concerned. BUT my niece went through a car-jacking in Los Angeles and it was traumatic.

One thing is for sure - my mom was very, very cautious and seemed to be on the verge of paranoia at times. I have wondered if growing up with my mom's fears have had an effect on me being more fearful.
