I knew here from earlier, because we both went to the same YMCA when we were younger. She lives a block away from me. Everyday when I walk back from the library, I pass her house. She says hi to me and I say hi back and continue on. She is cute, playful, and has a nice body and I know she likes me, because she always says hi first and likes to play around with me. Once she even invited me in, but I declined. I do not know or care wether she has a boyfriend. I am a focused man. What should I do after the "hi" part?
