Had a small garden party earlier - just a couple of pals. When it was just the two of us left one of my friend's mentioned that she wouldn't be able to go to an event (organised by her - I said I wasn't going at the outset) - apparently I said well that's what she usually did (her version, not mine) - she has gone in a right huff, stormed off and gone crazy. To be fair we had both had a couple of drinks and although what I said was true, I did apologise -she went mental and stomped off. Should I feel bad?
