Oh yes, how could I forget! My teenage son is also a Gemini.
I'm a Virgo, we squabble alot, often I find myself on his level because we actually bicker. None of my other children I do this with. It's just his character, he can be quite vindictive, spiteful with his words and whines alot. He will keep saying things until he gets the last word. I can say though, he is indeed very interesting, he can be very "soft" if you will, Warhorse made him burst into tears, so did Little Princess and still would, he is gentle to animals and babies/small children, he can also be VERY gullible. But he also thinks he is a gangster and portrays something really hard (which is anxiety hell for me as he can barely throw a punch properly) and pretends not to care but really he does and he cares deeply!
Also he has always been attracted to "fancy", highly decorated, often flamboyant things too. Ever since a very small child.
