I am owned as thoroughly as he. Equally, with different responsibilities and tasks.
Were I to abandon my new scarf by leaving it on a subway, it will no longer be my scarf. Someone else will pick it up, and it will become theirs.
It remains mine only so long as I keep investing myself in it and it’s care.
(Interestingly, the original meaning of “invest” is to clothe yourself with something, to enter into something that you wrap around yourself.)
