Says it all in the title, really. My partner's car broke down this evening. I've been at my sisters all day with the baby and I've come home to find out that he's dropped his brother off to the pub (he'll be drinking so of course can't drive) in his brother's car without being insured! 
I've absolutely hit the roof. He doesn't understand why I've got so annoyed, saying that it's 'only a few miles', but I just think that it's so so stupid and dangerous to do this! Now he's annoyed at me for apparently overreacting...
