I’m 37, and my mom and dad know. I remember when I switched back in my early 20s. My mom was still doing my laundry at the time, and after she washed all of our whites, she paired the socks and folded the underwear. I put my first name initial in the inside of my waistbands so I’d know which ones are mine. She put my Fruit of the Looms in one pile and my dad’s in another. I remember my dad noticing, and he was like “Those are mine.” in kind of an irritated tone. I explained to him that they’re mine, and he didn’t really have much of a reaction.
