Or the rune-rods which were "the medieval snapchat" https://www.nrk.no/vestland/gamle_-norske-ord-for-kjonnsorga... (google translate isn't half bad on this article)

or a more PG version https://sprakprat.no/2017/06/22/middelalderkvinner-og-runeku... where a rune-rod simply says "Gyda says you have to come home" (I guess hubby had been out too late with his no-good friends?)
