Could it be she was using the avatar previously, changed for awhile, then changed back wothout realizing you were using it?
Also, I do understand and would be miffed, too, but if the pic is on public domain, anyone has the right to use it. I believe I even have that same one waiting in a file to use but did not when I saw it being used by someone here.
Besides, I really like your elephants. No one else has them. Unique!
Beachlady, Would you be willing to keep your avatar even tho you don't live there anymore? We all identify you by it and besides, I get to go to the beach daily and dream.
