Keep in mind that I have been told, "You're a totally different person behind the wheel!" I will yell, swear, and honk at the drop of a hat. Other drivers need my guidance. Badly. One of my favorites: "Pick a lane, Captain No-Lane!"*
So my mom was talking to me and driving just now, and she blurted out, "Sir, why didn't you put on your blinker sooner? Sorry, I don't mean to be impatient with you, it's just a consideration to others on the road." When I asked her about her kind, calm, and thoroughly explained statement, she said, "Well, I try not to be impatient, 'cause I really don't like it." Touche!
*Although, I've improved quite a bit by reminding myself the simple phrase: You never know who has a bad mood, and a gun under their seat.
