from "j'ai rêvé (so I don't have to dream alone)", which apparently I'm not posting on Halloween after all (fucking bodies):

"Maman taught me," Adrien says. Maman is to blame for Adrien ever having heard this earworm, too. "Your hands go here and here—" He places one on his right shoulder, hooks his arm under hers, and takes her other hand. "—elbows stay forward, knees stay a bit bent, perfect. And I'm leading, so you cannot possibly step on my feet," he adds, mostly to get that exact amused huff.

The best bit is it's entirely true.
