... and then he came home with a gun.

Yesterday we canned applesauce.  Sort of on a whim, but sort of not, seeing as I've had a box of apples sitting on my counter for a month.  (Not Fuji apples; therefore, not the kind that Slice will eat.)

I had borrowed a strainer, jars, and steam canner from my mother ahead of time.  I even started boiling the apples.  But when we pulled out the strainer, there was a very important piece missing.
I sent Slice up to my parents' empty house to search through the storeroom for the missing part.  Or the other strainer that my mom has.  He found neither.
I called my sister, my aunt, my neighbor - nobody had a strainer.  By then I'd been chopping and boiling apples for almost three hours.  Slice left again, this time to the store to buy one.

An hour later I called him, wondering where he was.
(But not really wondering because 1 - he had just gotten a fat paycheck and 2 - every time he goes to the store he spends time at the gun counter.)
Which brings me to the real point of this post.  A question, really.

Do any of you live with a person who gets fixated on certain things?  And if so, how do you deal with it?
I like to think of them as phases: the remote-control airplane phase, the iPod touch phase, the dog phase, the new phone phase, the Modern Warfare 3 phase (AHEM).  But this gun one has lasted so long that I'm afraid it isn't just a phase.

I finally got so sick of hearing Slice talk about this gun or that one, watching (and making me watch) YouTube videos of shooting ranges and explosives, checking Basin Sports/Stewart's every time we were in the vicinity - that I told him he BETTER buy a gun after this paycheck OR ELSE.
Right or wrong, that's what I said, and that's what he did.
And then we made applesauce.
