Women - what hints have you given your crush that they missed?

The thing is, I seen all the hints I just didn't know how to act on them without making a mistake. I thought that was me giving a hint back. Turns out we both realized we were hinting each other and well nothing happened. 20 years later we talked about it but now we're both sad and in regret that we didn't do something, This post kind of brought that back. It's not your fault, but it reminds me.
