"Yeah!" Luka replies with enthusiasm. "As long as you don't let me drop!"

On Garrot's word he leans back suddenly. Luka feels his weight shift as his body position changes, and momentarily feels as though he might actually fall - the same feeling as when you lean just a little too far back in your chair. He scrambles back up as fast as he can, clinging to Garrot's shoulders like a seasick sailor who just found dry land.

And then he bursts out laughing.
