You often see women complain about how they drop hints to a guy they like and he just isn't getting it.

There were so many occasions where a female friend of mine liked a guy, and instead of telling him or advancing in any way, she just dropped "subtle hints" in hopes of him noticing.

The obvious problem here is that sometimes they just smile, or laugh at a joke you told.

And if you advance after some of this has happened, they sometimes say "so you thought I wanted to sleep with you just because I smiled or laughed?".

It's so confusing.
