Is cave exploration an indoor or an outdoor activity?

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Do I have to walk through the door? Can there just be a door at one of the entrances?
What if I enter a cave through a door installed in a doorway, but there are other entrances that don’t have doors?
What if you enter the cave through an opening where the door isn’t but I know the cave system has a door at one of the entrances elsewhere?
If you go in the door you’re indoors but if you don’t you’re outdoor.
This could lead to a strange situation where you enter the cave through a doorless entrance and leave through an entrance with a door, making the outdoors indoors in the split second before you fade from existence.
Go outside. Enter cave. Leave cave through another opening. Open door to exit cave. Explode.
Exactly what I said just less eloquent.
