The creepies of homeownership?

So, PoC was doing some work in the basement today and removed some old fiberglass insulation.  Tucked/hidden under it, he found....

a spoon, blackened on the bottom and bearing remains of a white substance. 

The house is 70 years old, so I'm sure it's seen its share of unfortunate things, but it seems creepy (and a bit pathetic) to think of some former resident getting high and then hiding the spoon away in the insulation...
