Most people will do that, hit your car with their door and not say anything like they think it's cool.
I had gal in a brand new bmw open her door into my valiant and pretend nothing happened 'while I was in the car'!!
she just smiled like 'oops'
I smashed what was left of my cheese burger and coke into her cowl so she could reminded for a while along with a lewgy into her cracked window.
