Missing someone’s birthday party is one of those things that feels worse the more you think about it.
A birthday apology message does two things at once. It says sorry for the absence and it also says, your day still mattered to me even though I was not there. The 49 messages below cover every situation, every kind of relationship, and every tone from warm and sincere to a little lighthearted for the friends who would appreciate that.
