history: I accidentally ate a piece of cake that my mom made for my dad as a special gift, I felt pretty bad about it. So the other day I ate a piece of cake that my mom made for my dad as a gift_comma_ oops. Oh no!  Well what he didn't know won't hurt him.  Hopefully you can get a replacement.
current: Unfortunately he walked in right as I took the last bite! Fortunately it all worked out so no harm done.
next: Awww well I am glad he was understanding about it.
