Finding a girl who's a programmer is like discovering a unicorn in your backyard. But dating one? That's entering fantasy territory beyond any compiler's imagination.
The meme perfectly captures that moment when your brain executes the most complex conditional logic ever: excitement about meeting someone kind and cute, absolute shock when she turns out to be a programmer (cue red-eyes panic), then complete system failure at the impossible scenario of actually dating her.
And then... the classic "it was all a dream" exception handler kicks in. Because let's face it, your chances of finding love with a fellow coder are about the same as fixing a production bug on the first try without Stack Overflow.
