I've never stood anyone up (that I recall) but I was stood up mid-date. Again, another one of those 17-year-old horror stories.
A friend of mine hooked me up with a friend of her boyfriend's (as the story tends to go in HS...and in life). We talked on the phone, everything was cool. We decide to meet at a local pizza shop for lunch (this was in the summer).
He rides up on his bike, after I waited for 20 minutes. We talk for 10 minutes, we order pizza and fruit punch and talk some more while we wait. Then he sees this girl he knows. They start talking, laughing etc. They step outside so he can watch his bike.
By then, the pizza's done, I've already eaten and am ready to go. I leave the pizza shop and he's nowhere to be found! I walk to the bus stop to go home and he's posted up on his bike still talking to this chick! I say to him, "so well talk soon...?" He just kinda half-nodded.
