Every couple of years, VorGuy will ask a question about something....that comes across the same way - if it's my "job" to handle that project, he does not retain the information overnight. It's like his brain runs Disk Cleanup and then deletes ALL the information.
This could be about a cake mix, a candy, a soda (pop), a computer game, or any of a hundred other subjects that "he" doesn't do the shopping for since that is (mostly) my job (he works - I am a stay at home mom - so my "job" includes running most errands - with shopping lists, sometimes he wonders why I haven't brought home something that he misses).

Him - "Why don't you buy Brand X any more? I like it more than this Brand Y."
Me - "Because the company hasn't made Brand X in years."

Him - "Are you sure? It really was better than this stuff..." back to fiddling with whatever it was that caused the comment.
Me -

"I can't get it any more, sorry."

He quit asking for Crystal Pepsi quickly. He still asks about some peach candies that the (family) company went out of business about three years ago (they were good - Peach Buds, if you were ever lucky enough to get them). Tiara Dessert mixes (for a couple of years - not the last fifteen or so - though he still mourns their rich chocolate cakes with Amoretta or Kahlua flavored mousse filling).
I still have the Tiara Desserts pan - but I haven't seen the mixes since the late 1980s (cake in a flat pan with a depression in the middle for a mousse type filling with some other kind of filling in a layer on top of that). I think I bought three of the mixes after getting the one with the free pan before they quit making them - if they were on sale AND I had a coupon. They were expensive mixes - but went over well if you were going to a covered dish dinner & were taking dessert.
I still have the pan and it is perfect for pound cake when I want to serve strawberry short cake.....or any other kind of dessert with a filling spread into the depression.....they just travel better across a town than across state lines.....
