You may find this hard to believe, but I don't go around correcting people all the time. I can think of one time that I did actually correct two of my sisters, though. It was done out of exasperation and after I had totally reached the end of my rope.
My two eldest sisters and their kids were staying with us for a long weekend. By "us" I mean my parents and me; I was about fourteen at the time. Each evening I would hear one or the other of them mention "bath-ing" the kids. "You can bath Bill and then I'll bath Sheila." "I'll bath Evonne and put her to bed, and we'll let Bill and Sheila play outside a few more minutes.", & etc!
On the last night they were there I couldn't take it any longer. I looked up from the book I was reading as Maxine walked past on her way to "bath" one of the kids. "You know," I said, respectfully, "it isn't 'bath', it's 'bathe'. Bathe is the verb."
Maxine raised her eyebrows at my fourteen-year-old presumption and asked, "Oh really?"
I said, "Yes, and it's been driving me nuts, everytime you guys say 'bath'!"
From the height of her 28- or 29-year-old superiority, she sneered, "Well, if it was 'bathe' it would have an . . . Oh!" There was a pause and she looked a little chagrined. "It does have an 'e' on the end, doesn't it?"
Maxine teaches first grade, by the way. lol
