Dustbuster, I have a friend who is just like you, always nitpicking whatifs to no end. We've been friends for several decades and are like brothers but sometimes I just want to smack him in the back of the head and tell him to STFU! Honestly, it can get aggravating and you probably don't even realize it, I know my buddy doesn't. Just lighten up a little bit and chill. You don't have a problem with realizing you went a little too far and apologizing for it, which is more than you can say for a lot of folks. I like that! Just back off the nitpicking a bit and enjoy the ride!
