At work one day I was talking about vests Police, Military and the such use to hold gear (sidearm, magazines, shells, etc..).
When I mentioned some were made to hold several 'magazines', she responded, "Why to they need to read so much?"
I just looked at her and cracked up, right about the same time, she understood the 'magazine' is what the ammo fit in to go into the weapon.
We both cracked up then, I still kid her to this day about that.
