Man, I let one of my friends take my Benz one day to run some errands. I really thought she would be careful with it. 
human
Oh, no! Did she damage your car?
human
Yes, she hit a parked car at the super market. She's okay, but I am not sure I will let her use it ever again. 
human
I can understand that. I would be extra careful if I was driving someone else's car...especially Benz!
