practical self: "this is just stuff. stuff that will accumulate and take up space. you don't need it. why are you considering this?"
treasure hunter self: "treasure!"
practical self: "how and when are you going to use these?"
treasure hunter self: "pretty!"
... and on.
This time, my treasure hunter self won out, with it's thorough, compelling, irrefutable arguments. So, for $16, I got this bell, letter opener and pin. I also found eggshell peacock feathers at another spot and splurged $6 on a pair. To me their lovely and I think that sometimes (as absurd and legitimate as the tug of war is) that's all the reason you need.
