Every Exit Is An Entry Somewhere Else

Every one knows the saying, when one door closes, another
one opens (or window, etc) ~

I'm just wondering ... there are people who keep themselves
in the same room, not opening any doors ... not exiting ... just
staying dormant.

I don't know if I reach my limit of exits ... or if opening so
many doors has gotten me confused of exactly what room
I want to be in.

Can someone go back to a particular closed door?
Can someone take an exit twice and not even know it,
therefore completely wasting their time?

Doesn't some exits also have detours, where you really
have no choice but to turn in that direction?

Drive On? Open Doors? Be Dormant? Close Windows?
