Ooooooops...
JW is always on me for those adjectives. When he sends flowers or surprises me, I would blurt out that "Ohhh, that's soooo sweet!". He has an immediate reply, always in a low voice, always with an emphatic tone "I'm NOT sweet. Guys are NOT sweet".
This is to say that if you wanted to say "I'm NOT a jewel. Guys are NOT jewels", you do NOT have to say it! I already hear it in my head.
LOL! Someday, I'll learn.....
