In this hypothetical situation Guy B was under the impression he was awaiting a response from Guy A.....trying to be patient and not to be pushy about the trade with Guy A.....then finally calls after a reasonable amount of only to find out that his offer was never received and the knife gone.

According to KRAZ "The potential buyer assumes responsibility that the seller acknowledges and understands the offer"


This was Guy's B assumption as Guy B sent 2 emails with the offer and now that is why Guy B is...I don't have the words for a family forum.
