Show your niece that you care with an apologetic belated message. Everyone forgets birthdays sometimes (or simply can’t get in touch with the person they want to contact until after the fact). So, if you won’t see your niece on her birthday and aren’t able to wish her a happy birthday until afterward, send along your hopes that she had a wonderful day instead.
- Happy belated birthday to you, my beautiful niece. I’m sorry I couldn’t celebrate in person, but know that I’m wishing you a magical year ahead.
