Dont feel too bad , i was topping up an old civic i had , took the oil cap off , put it to one side , and put the oil in , wiped around the filler cap , turned around put the oil can on the ground , and then shut the bonnet ...
only discovered it a week later when i was topping up washer fluid ..
and i used to always leave the petrol cap on the roof and drive off ....
id forget my balls , if they werent kept nice and safe in my girlfriends .... purse
