Ellbell,
No worries
I'm also quite the pedant when it comes to my own writing and I do notice and grit my teeth at grocers' apostrophes (or was it one grocer that brought about that use?), prefer to queue with 10 items or fewer, have rejected a suitor who wrote "your so pretty", and the infer/imply mistake almost makes me lose my reason [although that's kind of different, because that mistake really causes sentences not to make sense], different from/to is not one I care about, but I'll probably start now: I collect these things
And when I taught English I sought to teach my students how to write correctly as well as clearly. The classroom is the right place to be pedantic about getting things right. Students love it. [really, deep down they do]
Still and all I see a lot of meanspiritedness in threads like these. Some people really do get a boost to their sense of righteousness and take it away and do abuse other people for making mistakes when they are having online conversations. That makes me sad.
As for teasing your DH, I tease mine for not being able to pronounce his Rs at the end of words and other strange Britisher ways he has. It's fun, I do realise that.
Also I am just contrary, so where lots of people agree in harmony I just have to step in and ruin it all.
