when I went down to the Michigan skid school about this time last year, we traveled in a rented vehicle. We stopped for dinner and when I went back to the car I opened the door to find a lady looking surprised at me. Turns out I opened the door of the wrong vehicle! I apologised and turned around red faced to see the guys in our car laughing at me. Might be the same thing happened to your grandfather, just an innocent mistake.
So yes, some of us absent minded people do that! LOL.
Dont talk to me . i have done the same thing my car was parked and so was another one almost the same . over i went and got in and a fella about 14 was looking at me and i was looking at him. and there was me asking him who he was and what he thought he was doing? red faced or what..???
And one other time i was trying to open a car which i thought was mine and could not figure out why the key wood not open the car door.
