I bought some walnuts a while ago from a certain store. It's healthy enough. Those ran out. I bought some more. Tried some different kinds of nuts -- hazelnuts, peacans, etc.
When you cut the bag open, the nuts might fall out. I didn't bother with a twister or anything to close the bags. Just spin them and put them back in the original grocery bag I got them in just in case any spilled out.
So a moment ago I cut open a new bag, carefully spun it around but it would probably open and the nuts could spill out.
What thought crosses my mind? "That's going to spill. The bag will come undone. I'll keep them in the original grocery bag since it looks different. it's easy to tell it apart and I'll know the nuts are in there, potentially spilled out of the original bags. That's like the special bag for nuts. That's my... nutsack?"

And then what I just thought sunk in.
It is my nut bag though. I'm still not messing with twisters. But the original bags will still spill, and I've got this distinctive bag here...
