BUY Five or High Five?

At a social event last night, I managed to sell 2 copies of my book (Please don’t start avoiding me. I am still sensible and will back off if my potential book buyer is not interested).

I told someone that my books are sold out for the night. Technically correct – I only carried 2 copies with me. I heard the person responded “Yes, BUY five” with one hand/five fingers up. I said, “sorry, sold out tonight. Will arrange 5 copies tomorrow!” He said “No, I said HIGH five” As some people said, one tends to hear what they want to hear. Perhaps next time, it will be really 5 copies of my book!
