Last week OH's neighbour brought her over a piece of a cake she'd made, and asked if I was there, In which case she would bring another piece for me.
OH said I wasn't, but would be there Friday so she said she would make another cake for me for then.
As it happened, Friday was OH's birthday, but neighbour didn't know that.
Being mother's day last Sunday, there wasn't much choice of birthday cards when I went to buy one last week, as they had mostly been replaced with mother cards.
But I happened to find one that just said "Happy cake day" on the front, which I thought was a bit humorous, hoping that the neighbour would remember MY cake.
It all had a happy ending, because she did bring me my cake (and some for OH of course)
