We shopped yesterday. Separate cars. When we got home I gave my wife the usual haranguing about driving in the left lane. She says, "But the headlights blind me in the outside mirror." I have told here time and time again how to set up her mirrors to avoid that, but it's not how they taught her in HS, and she wants to be a good driver.
The other peeve I have is: The drive home from E'ville is really boring. All I have to look forward to is the one really fun offramp when I leave 41. I just hate it when Mr. Idiot Coal-Hauler or Mrs. Grannie Caddilac just
has to block me so he/she can get there first.
-But-
Ron was right. I get annoyed at oft-encountered doofusness, but there's absolutely no point in getting enraged. Try to be the good example whenever possible. If we get upset at every little thing - well there's just too many little things out there to let them take control of our character.
