(CNN) - President Barack Obama may be out of office, but he's keeping up a tradition that means a lot to a lot of people.
Twitter this week discovered that Obama's office has been responding to wedding invitations for all eight years of his presidency, and hasn't stopped despite Obama no longer being in office.
Brooke Allen tweeted out a photo of the response her mother received after inviting Barack and Michelle Obama to her wedding.
Soon, others joined the online conversation with similar stories and photos of their letters.
The letter reads, in part, "Congratulations on your wedding day. May this special time be blessed with love, laughter and happiness. We wish you all the best as you embark on your journey together and we hope your bond grows stronger with each passing year."
The response was particularly meaningful for Chelsea Roden and her wife, Lisa, since same-sex marriage was legalized during Obama's administration.
Obama's office has also been known to respond to graduation and birth announcements.
On Friday, the former commander-in-chief turned 56. We'll see if birthday cards get a response as well.
