The other day I went to a shop near my house to meet the guy and saw a car as I was walking down, in the closest of the 2 parking bays opposite the shop where it's dark.
Someone was in the car and looking at me so I walk over, keeping eye-contact all the time. I thought he waved or gestured.
I got to the point of opening the door and leaning into this guy's car, and then realised it wasn't my friend. I apologised and told him I thought he was my friend, who was in the 2nd parking bay.
Funny thing was that the guy who's car I accidently nearly got in really smelt of skunk and he was sitting in a dark car park on his own with his engine off. Made me feel less awkward about the whole thing haha.
