lividlillies said: Lack of a betrothal necklace on Toph is fine. The necklace is a Northern Water Tribe tradition (Sokka and Katara only realised its true purpose when they went to the N.W.T and found out their grandmother had gotten hers from Pakku), and Sokka is from the Southern. They might have different marriage customs. ^^
I’ll accept that.
But one of my favourite headcannons involves Sokka making a betrothal necklace for Toph out of space earth. So… Yeah. But you do have a valid point.
