things that are special to me

Today is the day that a boy gave Annabelle an acorn at school. Kind of like Peter Pan and Wendy. She told me about it after it fell out of the small pocket in her middy blouse while she was cartwheeling. She carefully put it back, gave it a pat, and said:

"R_____ gave me this. I put it in my pocket because it is special to me and I want to keep it safe."

I know what she means, but my pockets aren't big enough.
