Not a question, more like a useless piece of information that doesn’t fit on my blog but I’ve never seen it mentioned that the human kids guardians all follow a three letter rule. Mom, Dad, Bro, Pop and Jade even made Bec fit the rule by shortening his name. But anyway....

Not really though, Grandpa is called GRANDPA in Homestuck, and just PA in Hiveswap, as far as I can recall ‘Pop’ is only used for John, as Poppop.
