Tip #1 when walking into a crowded party: Head straight up to the bar, help yourself to a drink, relax, enjoy. Repeat.
Right? Yes, obviously.
Well, now it turns out that logic might be flawed. A study at the University of Illinois at Chicago found that college students who'd had a few drinks, enough to get "intoxicated," couldn't read social cues in a series of photos that showed angry, happy, scared, or neutral faces. They got people's expressions all mixed up.
The consequences? Anything from an embarrassing rejection from someone you thought was making eyes at you, to a full-on fistfight with that innocent, smiling stranger in the corner.
But don't say we didn't warn you.
