i couldn't help myself

my grandson moved back home last month, and now there's this girl staying over at his place who must be around 20 years old. every time she walks in the room with her bright smile and bubbly laugh, it feels like springtime again. i catch myself smiling when no one is looking. but of course i would never say or do anything about my little crush on someone so young. just thought maybe it's okay to have these feelings, even if they are a secret.
