when i was in survival training for the first time
i had to take a shit.
i asked mike the guy in charge what could i wipe with.
he gave me one fucking square of paper.
i walked a ways and did my thing.
when i came back he asked me
"wheres your paper"
i said " i buried it "
"go get and bring it here and burn it " " leave no trace "
first of all its hard to get real clean with one square but do-able
second its nasty to walk with shit-paper in front of another.
then to burn it is quite humbling
