You go to the party with your girlfriend.
After 20 minutes she disappears. Nowhere to be found.
But you keep calm because "she would never cheat on you". Plus you know everyone at the party they are your buddies.
Except for that black dude you saw earlier, first time seeing him.. but my girl "would never go with a black guy". It's all good have a beer.
You've had 3 beers and she is still not back. It's been an hour now. You go and start searching all bedrooms upstairs.
Here she is..
