OMG, really? I'm SO SORRY! I hope you forgive me, I'm really really sorry!
i always correct people. i cant help it! this one time at school we were being given a talk on something and i was in the front row and the teacher said 'me andmr wood' and then without even realising i said 'mr wood and i' and i accidentally said it kinda loud and then he looked at me and was like 'excuse me???' and i was like 'umm... is just that you said me and mr wood and its mr wood and i... ' and then he death stared me and a few people giggled and then an english teacher was like 'haha good one jess' and yeah thats my story!!!
hahaha correction fluid! thats kinda funny!! and quite interesting too.
i usually tell the correction to the person sitting next to me even if they aren't the one who needs correcting... and then that person usually does one of those massive annoyed sighs... hahaha
