Here's one..
My MIL grew up in London and says "I done it" Now as far as I know (I'm from Yorkshire) it should be either "I did it" or "I have done it"
It's never been a huge deal except she has brought up my Dh to say "I done it" too and I don't want him saying this in front of DS (who is 2) as I do not want DS to grown up saying it too.
All the nieces and nephews who have been brought up by SIL's say "I done it" and it really grates on me cause I know it's wrong but I cannot explain why...
Can someone help me?
