Child/Teen crushes

Any of y'all have some weird/strange things you did as a child (or teen) when having a crush on someone?

When I was 9, for two years I kept a picture of a boy I had a crush on, cut out from the school yearbook, inside a locket necklace. The locket was too small tho, so I had to fold the picture twice and sometimes I’d take it out just to stare at it and daydream.

When I was 14, there was this girl in my class that I thought had the most beautiful hair - it was a strawberry blonde and looked like it was glowing in the light... Thus I snatched a strand of fallen hair and kept it.
