I can't eat Butterfinger, for a reason that might sound silly to some.
My grandmother's favorite candybar was Butterfinger, and the only time I can remember eating them is when she bought one for her and one for me. As she got older, it got harder for her to eat them, so one time I bought her the Butterfinger Crisp. She could sort of let it dissolve in her mouth and still enjoy it. It meant a lot to me to see her enjoy something she thought she could no longer enjoy.
After she passed, I bought a Butterfinger. I couldn't bring myself to finish it because I felt it was a "Grandma and me" thing I was doing without her. My eyes are about to tear up as I write this... But yeah. I haven't eaten a Butterfinger since she died.
