My memory is starting to play tricks on me and this was one of those tricks. I spent the whole week thinking about your birthday and then on the day it completely slipped my mind.
I am sorrier than words can express. Belated happy birthday!
Had I known forgetting your birthday would’ve caused so much trouble I’d have tried harder to remember it! I definitely won’t miss another one, that’s for sure!
I can’t believe I missed the birthday of someone so unforgettable! I’m sending extra special belated birthday wishes your way to make up for it though, my dear!
I’m sorry I couldn’t be there to wish you a happy birthday on the day, but I’m sending you your birthday wishes anyway! Belated birthday wishes to you!
I wasn’t sure how to wish you a belated happy birthday, but I thought it would probably be best to start off by apologising for missing the actual day!
Sorry for the late wishes, I hope you can forgive me! Happy belated birthday!
