This reminds me of someone who used to work with me. She'd stare at me while I was working, and then I'd turn and she'd keep staring at me, and then she'd let a "Oh my God, you're so fucking old". She was in awe I was still alive and amazed by my old age. I was 29 at the time.

She was in charge of hiring campaigns, would come to the manager and tell him that someone had applied "but he's like old" (in his thirties). The expression on her face was as if it were a contagious disease or something; as if merely reading the résumé or saying the age out loud decreased her lifespan or endangered her life. It was hilarious.
