Who changed my personality without telling me?

I looked into the kitchen draw this morn­ing and found a odd lit­tle thing. It is black, and cylin­dri­cal, with a sil­ver stick­er on one end. I looked at if for a while, then I picked it up and looked at it clos­er.
I had abso­lut­ly no idea what the thing was. This isn’t an unex­pect­ed occur­ance in a shared house. And was­n’t the thing the real­ly freaked me out. What got me was that I put it back and had no inter­este in find­ing out what it was.
It’s still in the kitchen draw and I’ve not made any sort of inves­ti­ga­tion at all. This isn’t me. Or at least it nev­er was… some one has stollen my curios­i­ty.
