[Nothing wrong with a healthy dose of doubt. Kai turned to watch this shifting around as he plopped the last gummy bear in his mouth, chewing on it thoughtfully.]

Side by side or back to back's probably better cuz its easier but--

[It was Kai's turn to twist his position, sitting with his shoulder against the side of the bench. When he moved to lift his arm it was a bit exaggerated so Cliff could see it wasn't going anywhere drastic, just moving to rest on the bench like an elevated arm rest. It was just also running next to Cliff's foot, making that point of contact that was otherwise missing.]

Long as there's contact, that seems to be what works.
