I leave lipstick stains to mark my territory: not on any significant other, not even on cups or water bottles, but on the cheeks of my mom and dad and brother if he'll let me.
I have a stick of dark purple, and another of bright pink, and when I say my "good bye" and "I love you," I leave a ruddy mark.
My dad brags about me, he says, "My senior still talks to me," and when I hear this second-hand I preen and call him and talk to him some more.
My mom is the one who tells me this, and she laughs at my antics, me swelling up in pride, because she thinks I'm hilarious.
Later, I wave in at her while she's in some important meeting, and she smiles and waves back, along with three other members of that committee.
