Hypothetically let's say you had a bottomless bag, but see, half of what went into it would never come back. With no way of calculating when or what it might snatch, just a 50-50 coin tossed in infinite black. Til everything you keep becomes a something you lack, with no way of keeping track of what's all trapped in the fabric. Since you can't recall a thing you may or may not have stashed, would you reach in it and risk your hand and wrist get detached?
