And in reading your comment, I just realized there's a difference between casual conversation and writing something down. I can easily say "Hey, let's meet next Wednesday!" and you may reply with "Oh, great, I'll put it in the calendar, the 8th it is!" and you reply with "No, I meant the 15th" -- and this reduces the ambiguity. This kind of thing would be happening in "real time", so being perfectly clear isn't as important. However, if you write "next Wednesday" in a contract, and then complete it on the 15th instead of the 8th, and it's taken to Court ... it's a lot harder to figure out what the the original conversation was like, that led to the writing of the contract! Hence, it makes sense to use as unambiguous language as possible when writing a contract.
