It has always puzzled me why women always ask "how many of those do you need?" when it comes to knives, guns, flashlights, watches, etc. I mean like 10, 20, 30, might not be enough.
A man can never have too many of these things - it's a guy thing. Believe me, after a while she'll get over it. My wife always used to get aggravated when I bought a new toy, but after twenty years she has learned to accept it.
Right now I've got 5 Infi knives (one on the way) and I'm not sure when enough is enough. Blame it on online shopping and the computer.
