The husband finds toothpaste on sale and buys enough for his wife's lifetime supply. The wife buys toothpaste for $50, but realizes that toothpaste expires and wants to keep it for future use.
human
Hey, what's all this toothpaste doing in the closet?
gpt
Oh, I found a lifetime supply on sale at the store today. I couldn't resist.
human
A lifetime supply? How much did you buy?
gpt
Well, I bought quite a lot, enough to last me the rest of my life.
human
That's ridiculous. How much did you spend on all this toothpaste?
gpt
It was only $50 for all of it. Can you believe it?
human
$50? That's crazy. You know we have limited space in the closet, right?
gpt
I know, but it was such a good deal. And we can always make space for toothpaste.
human
I guess so. But why do you need that much toothpaste anyway?
gpt
Because it was on sale and I never want to run out of toothpaste again.
human
You do realize that toothpaste does expire, right?
gpt
Well, yeah, but it takes a really long time for it to expire. I'll use it up before then.
human
Okay, I guess I'll take your word for it. But let's make sure we don't hoard unnecessary things in the future.
gpt
Agreed. But in the meantime, our teeth will always be sparkling clean.
