When it comes to dating, what are the biggest hints or clues that you've missed in the past?

One embarrassing "hint" that completely went over my head at the time:

I was on the second or third date with a girl and was over at her house while her parents were gone. It was a big old two story house and we were in the living room talking before we went out. She showed me a hole in the ceiling and said that that hole went right into her bedroom and that I better not look. So I didn't.🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️
