Very good point. Now that's a clear distinction between "before" and "in front of". And considering what Casio said, we can see that "before" and "in front of" are not actually synonymous. Still, there are those times when they are used to mean the same thing, and there's nothing wrong with that.Originally Posted by blacknomi
In that case "before" is not "in front of", yes. However, it's still possible to think that the blackboard is located before the students. Most likely no one would say that, but it's possible to think of it that way.
However, if you turn around and see something rather surprising written on the blackboard, you could say, "I couldn't believe what I saw on the blackboard right before my very eyes." And the blackboard would, of course, still be in front of you. You would still be in front of the blackboard as well.
It's this secondary use of "before", as in "speaking before a live audience", that would seem to cause confusion.
