QotD: You Never Get A Second Chance...

When has your first impression of someone turned out to be completely wrong?

A while back, I was a member of our local Hazardous Materials Response Team.  My husband was also a member, but for a different agency.  One call had us going to a local discount department store because some one had put pool cleaner, as well as a truck load of other weird stuff (bowling ball) into the cardboard crusher baler.  Pool cleaner has powdered chlorine as well as other bad nasties.  Anyway, a newish firefighter that works with my husband was on scene when I got there and started giving me a ration of sh*t.  I totally went off on the guy.  Thought he was the world's biggest a$$hole and told him so.  Not a good day.

At the time I had been a firefighter for about 15 years and was really tired of having to prove myself to every new guy that showed up.  Grrrrrrr.  Long story short, after I got to know him better, heard his story etc.  I have changed my opinion of him completely.  A nice guy, loving dad and husband who's life has been a whole lot rougher than I could even imagine.  You'd want this guy with you in a bar fight, fire fight, whatever.  Boy, was I wrong.
