Same here, I used to only say "babe" if I was taking the piss but now I'm around babies and young kids, I've been accidentally calling them babe without thinking! It's such a gross betrayal, I don't know why it's happening. I'm also trying to remember to call little girls strong stuff like champion instead of princess, but it's just hard to remember all the time.
I absolutely hate people using "how's it going" as a greeting, especially when they say it as they walk past or away from you so you have to decide whether to just ignore it or to yell "fine than you and you?!" into the distance between you.
It should be a punishable crime.
