foiled by randomness

it is definitely not my ambition in life to take things back to stores on a regular basis. unfortunately, it seems like i keep buying things that are totally ruined either the first day i own them or even before i even picked them up in the store. am i just not paying attention any longer? i used to think it was crazy that someone could mistakenly purchase diet soda, for example. it's been a long time since i decided that was not the case.
