I had a parking spot at my job, but I didn't have a car.  Another friend decided that he would use my spot since I wasn't using it.

Maybe you can park a bicycle or skateboard there.

I thought about it - but then my friend decided to park his new car there!  I'm pretty upset about it - it is my spot after all.

Dang! Tell your friend to go find a new spot!
