I used the word "glazing" yesterday, referring to windows inset in a garage door: "I like the one with the glazing in the top panel". Wife & M-I-L looked at me in bewilderment. Apparently "glass" or "windows" would have been fine, but "glazing" not. I've only been in the US 14 years. Still a NIG, it seems
Edit: just to add to that none of my Brit friends think I am a Brit, even after showing my passport.
