[poll] what did you forget to pack?

Whenever you head out to an adventure in the wilderness, what is item you forget to pack in your shulkers most often?

Not sure how, but this post got posted live before I had finished adding on choices to the poll. So feel free to leave comments instead of the poll

Definitely an Enderchest. I usually have the items I need on my person, but if I need more, I always forget that they are in my Enderchest. Usually I forget to bring one to access said items.

torches! ALWAYS torches!

For me it is always the enderchest. I went to the end a couple of times, collected a bunch of shulkers shells and other goodies and then when I call it a day, I'm like wait.....how am I gonna get back, and you might be thinking, "Oh but there's enderchests on the end cities!" Well good luck finding them AGAIN, because I sure CAN'T! Once I leave a city, its gone forever to me!

So I die, get ANOTHER set of adventuring stuff to get the stuff I left behind, this time with an enderchest, and then proceed to go back to the end, wonder which portal to the end cities did I take "was it this one? was it that one? oh what the hell, whatever!" and finally I can get back with the stuff I looted. This has happened quite often.

Extra fireworks weren't an option? Nor is EXP bottles to repair Elytra on the go?

As for me: my toothbrush.

In Minecraft, I never take anything out of town exploring. I prefer to gather everything myself. Sometimes I do take voter's armor, though, and rarely tools.

I never unpack, so I do not often forget things... but if I do it is typically armour as it is the only thing I take off when in town

And to those of you that forget enderchests, doesn't that mean you technically forget everything? haha

EXP bottles.
For repairing elytra, of course. I seem to have no shortage of rockets and will have at least 9 extra stacks in my inventory than I need. But my elytra always runs out of durability.
Also a boat. Ice tracks use what? That's right, they use boats and I always forget one...
