When you read your posts back to yourself (in your head, not out loud) how do you imagine you sound?
I don’t know why but I read my writing with an English accent, like a proper English lady sitting down to tea and crumpets. I don’t especially like an English accent. Maybe I just see myself as prim and proper, more than I really think I am.
PS- You should be reading your posts back to yourself. If you aren’t, start doing it. Spell check isn’t enough!
