Toph is holding onto you for some godforsaken reason, even if she's blind, she knows damn well she can use her earthbending senses to feel her way around the house. She's just holding onto your arm and not doing much else.

You: "...You've held onto my arm for the last 3 hours, and for all of those hours, you've done nothing but that."

Toph: She just blows a raspberry at you then lays her head on your shoulder.
