Core Memory?

So like I think I just made a core memory.  What happened was my grandmother was feeding her new cat (originally a stray but now chills on the porch) and she invited me to try and get the cat to let me pet her.  And so I was kind of just chilling there while kitty was eating and when she was halfway done, my grandmother came over to the bench on the porch where kitty normally sits so she'd come near me.  Kitty came over when she sat on the bench and Kitty was super affectionate to me.  Me petting her went on for a little until my grandmother went inside to work on taxes ( I think that's what she's working on) but after that Kitty kept letting me pet her.  It went on for a while and she even let me rub her belly!  I had to go back inside for lunch after a while but that was a super nice experience
