Thinking it over. Hmmmm .... I would consider "stunning" a compliment.
Considering further it came to me I was not told I was stunning until I was well out of my teens. Before that I had my share of compliments but ... do you think a teen could be stunning or does it take more poise - more maturity - to be a stunning woman. Stunning teen doesn't feel or sound right to me! As for these days I am delighted to hear "Lookin' good!"
