I listen to language very carefully

No, sorry, that's a charming story you tell yourself but I have listened to you making grammatical errors and speaking in non-American colloquialisms (like "I'm listening to language carefully since I'm eight years old") for fifteen years.

And please, stop flattering yourself that you're "the only person in this room that is bothered by 'very full'." It just isn't true, and you're unconsciously lifting yourself up by putting others down. If you don't have any friends who are particular on their grammatical points, then you must be surrounding yourself with people who are badly educated and intellectually lazy. Why?

And there is such a thing as a "full glass" that isn't loaded to the brim. It's functionally full, nearly full, very full, and so forth. If you want to use precision when linguistically we use the word "full" to mean a range of fullness, then you can tell how many ounces of water are in the glass and how much empty space is at the top of the glass and THEN you will put us all to sleep but please stop flattering yourself that you're the only person in America who knows the meaning of the word "full" ... or "unique" or "antique", for that matter. It's so bloody annoying.
