Oblivious Tango
It takes two to tango but only one is blind. Usually the girl is so clueless she thinks she's doing the whole dance by herself and the guy is just standing there like a confused idiot.
She kept winking at him like he was her best friend but he had no idea she was trying to flirt.
He was staring at her like she was a ghost but she thought he was being weird.
She walked past him three times and he still didn’t get it.
