why is it when you move a meeting or something to a half hour later you "push back" the time? if i say "let's have a meeting at 1pm" and then my boss says "let push the time back to 1:30", what the hell does that mean? wouldn't you be pushing the time AHEAD? or if you decided to have the meeting at 12:30, wouldn't THAT be pushing it back? hello? am i missing something here?
