I was once driving along fine in the left lane and my female friend in the passenger seat suddenly yelled "TURN RIGHT HERE. RIGHT HERE! RIGHT HERE!!!"

So I cut across two lanes, avoided several oncoming motorists and made a hasty but decent emergency right turn into the parking lot.

She looked disgusted and said "Why did you do that? The place is RIGHT over there" and pointed to an area on the other side of the street on the left of where I'd been. "Why didn't you turn left RIGHT THERE WHEN I TOLD YOU TO!".

Ah, I loved that girl (platonicly). She hit me with a shoe one time, but I still feel bad for who she married.
