And now you understand why older men dating young girls is creepy, even if legal.
They have nothing in common. There's no way. It's pure physical attraction above all else.
Edit: Seemingly a lot of older people down voting this are in denial about how much they have in common with some 18 year old girl/guy as a romantic partner. You understand you're not fooling anyone, right? Not even other people like you. Underneath, you all know what you're about.
