How to Explain This

Draw a picture.
If you think you're too smart to need to, you're wrong.
If you think Joe over there understands what you're saying, you're wrong. You should draw a picture.
If you think you understand Bob, you're wrong. He should draw a picture, write it down, look at you and ask, "you know what I'm saying?"
My basic rule is if a design requires me to stash things in little cubby holes in my brain while someone is explaining it, words alone won't cut it. Example: "a queue is going to hold 50 items, and it's implemented as a table, so we need a stored procedure to update the date if it's already there, otherwise we'll insert --" STOP. Draw a picture, man, PLEASE.
