Romance movies
Why is it in romance movies, the man is a clueless idiot who doesn't know that the woman he should be with is the one

• he is working with or
• is the best friend of his fiance or
• is the waitress

But the woman in question is clued in on this but is just making the man agonise a bit more.

The man is a clueless idiot who is

• pursuing a woman
• going to marry her
• seeing her casually

but the woman he should be with is the one

• he is working with or
• is the best friend of his fiance or
• is the waitress

Yet the woman in question is clued in on this but is just making the man agonise a bit more.

Conclusion: If you see a film crew filming you, get out of whatever relationship you're in and bonk the waitress.
