I do a lot of writing at work and I do even more proof reading and editing. One of my pet peeves is seeing only a single space after the end of sentence punctuation/end marks. I don't consider myself old (early 40s), but lately it seems the generations after me are being taught that it is acceptable to use only one space after an end mark. All the reputable grammar guides say the same thing. It is okay to use one space after a period, question mark, or exclamation mark. Okay, so it's acceptable...it still irritates the ever-living-crap out of me. I still correct the writing as such as I prefer. I have even noticed that word processing software is also formatting as such. I consider the fine Ladies and Gents of Badger & Blade the most intelligent in all the land. What say you!
