I don't have any advice, but I thought I'd pop in and say that my darling group of students consistently point out to me when I use the wrong word, and have informed me this week that I've been very forgetful lately (they had to tell me the date, and remind me of our schedule, and informed me that I wrote the wrong weekday on the whiteboard, etc etc). I'm grateful for it, they get a little laugh and I get corrected!
