This birthday message arrived a little late

This is a birthday message
That arrived a little late,
But wishing you happiness
Really isn’t set by date.

I hope you had the most fun
And celebrated in a great way
The fact that you were born
So many years ago on that day.

I sincerely apologize
for not remembering,
It was your special day
I ended up forgetting.

This message may be late,
But I must say this to you:
Every little word is heartfelt,
Every little word is true.
