Are you a strict grammarian?

That being said, I have a dark confession to make: I use two spaces after a period.  I know it's wrong, but I just can't help myself.

Don't feel guilty.  Using two spaces between sentences is fine, if perhaps a bit antique.  Yet, I like the look, and it does serve to distinguish between a period used to end an abbr. and one used to end a sentence.  Long live dual spacing!  (As well o t h e r forms of traditional spacing that have declined.)

BRTD is literally the worst. I could care less what he thinks.

So you do care!

(BTW, as irksome as it to me when people use "could care less" when they mean they don't care at all about something, even worse is when people ironically use the phrase to irk people like me.   But irregardless, I know my language use likely sets off some people's peeves as well.)
