Another thrilling minimalist question!
Do "Dexter Donuts" count?
If you don't know what Dexter Donuts are, they are things you take to work and/or put in your cubicle/office to make you appear likable and/or normative.
In the show Dexter he would take donuts into the office. This way he endeared himself to others and they would not know he was a super-hero/serial killer. haha
At my office I have:
Pictures: Me fishing, me fishing with my dad, me canoeing with friends, me at various travel destinations, me with my current ladyfriend, my ladyfriend.
Magnets: flags of nations I traveled to, an Orioles magnet, a Thoreau magnet
Art: A print picture of James Thurber and his prose, a mug with Kurt Vonnegut drawings/pics/quotes
Misc: I have a few pics of well-known folks and their quotes outside my cube (Neil DeGrasse Tyson, William F. Buckley, Jr., Elon Musk, Maggie Thatcher).
Should these items count as my possessions? They never leave work. Most are 2 dimensional.
