Sorry- this made me burst out laughing!
It happens to me toooo- except not in cars, because I dont have one!
I read the post as 'car', carried on, thought to myself that can't be right maybe she meant 'cat', went back, realised I was right, carried on reading, then realised this subject had already been covered by others.
Its been a long week.
Also, Im kinda glad a cat didn't eat your earring because...well, poor cat. It might of choked!
