When the word 'too' is the last word in a sentence, is it preceded by a comma? I see it both ways all the time.<br/><br/>He wanted to go to the movies too.<br/>OR<br/>He wanted to go to the movies, too.<br/><br/>I also see this one written both ways -- with and without commas. Which is preferred?<br/><br/>I, too, like apples and oranges.<br/>OR<br/>I too like apples and oranges.<br/><br/>When the words 'in fact' appear in a sentence, is it set off by commas? 1 or 2? I also see this both ways.<br/><br/>He was in fact responsible for her demise.<br/>He was, in fact, responsible for her demise.
