When I was like 18 I brought a girl to my house while my family were away for the weekend. I wasn't intending to do anything with her, I'd just invited her over for some company as we'd be speaking for a couple of months and had already been out a few times together but not exactly on "dates".

Anyway, I ordered some pizza and put on a movie. Next thing I know, she's cuddling into me and I'm stroking her hair. At one point she is laying across my lap gazing up at me.

I didn't fucking kiss her because I'm a damn idiot who couldn't take the hint. She couldn't have made it more obvious that she was waiting for me to make the move. I'm not autistic myself, just a regular moron.

We gradually stopped talking after that night. I blew my chance. Shit still bothers me years later. She was super sweet and pretty. Best girlfriend I never had.
