In this week’s yearbook Twitter update, we find more great practical uses for the yearbook.

That includes using the yearbook to take a look back at that glorious decade known as the 80s and also figure out who that mysterious Facebook friend request is coming from. Oh, and don’t forget to order your yearbook!

@negativelane: Can I say that (looking at my high school yearbook from 1988) the Eighties were not kind to hairstyles or fashion options.

@The_Ausmerican: FB friend request mystery solved thanks to the good old HS yearbook.

@OTOOLEFAN: Quote my Mom chose for her 1949 high school yearbook: “Private sincerity is a public welfare.” Miss you.

@Kristin_Brooke: ohmygod, ugh. I can’t believe I forgot about yearbooks. If I can’t get one I will legit spazz at someone, idk who yet.
