I had an idea for a story in which, after not seeing each other again after leaving the friendship school, save for Gallus and Sandbar who both lived in ponyville, the students are reunited by Gallus for hearth's warming as a special gift to Sandbar who helped him a lot to put his life in order ; but I couldn't do it in time for Christmas, so instead have a drawing of adult students looking at photos from the time they were still students at Twilight's school.
