I am also one of those who will tell people things when I heard they are trying to do some thing that they have no clue about what they are doing. My DH has no problem with it, but my kids do. I get the rolliong of the eyes and :MOM" and I know what they mean. I try to explain them they have me, and when they need to know something I get "THE PHONE CALL" most of these people don't know anything. They are just on vacation. No Info at all. I really have meet some really nice people this way.
