would understand the sentence I wrote. I kid, I kid. I use 2 spaces because it is aesthetically pleasing. I throw away any cover sheet/resume that only uses one space. So I don't view it as wasted space.
My last sentence refers to the fact that abbreviations end in a period "." and if that period is followed by two spaces then it is clearly at the end of the sentence but if you only use 1 space then it is technically possible, although probably pretty rare, to introduce ambiguity. Now, as can be seen by the multitude of errors in my writing, I am not a grammar Nazi. I'm just trying to protect the 2 spaces lobby.
