I dated a girl a long time ago who had a friend that one time clogged the toilet up with shit when she was young. She flooded out the whole upstairs in their apartment and her dad got super pissed off. It drove her to have such a phobia of shitting and clogging the toilet up that she started shitting in bags, and hiding it in her closet and would get rid of them when everyone was gone. Eventually, she got lazy and her mom found some shit bags in her closet hidden and confronted her. I feel like that drove her even into more paranoia and it just got worse. I don't know how that ended to be honest, because I stopped dating that chick because she has weird friends. But the bottom line is, I feel like that is very close to what we are seeing with this gas in a bag situation.
