if you use all the ice cubes and don't fill up the ice cube tray... the next time you want ice cubes, there won't be any*
it's also true that if you use the last of the toilet paper and don't refill the roll, the next time you're looking for TP, there won't be any*
** unless you have an ice cube/toilet paper fairy and let me tell you, that person may just be harboring anger towards you that could show itself at unexpected times.-----
