"I promise it will suit you." Yussa gives Caleb another kiss - a reward for acquiescing. He stands straight again, though given the height of the bed, that doesn't make too much of a difference. A smirk quirks his mouth when Caleb calls him an old man, and he is quietly playful, verging on flirtatious when he says:

"Don't be impertinent."

He does like Caleb Widogast, and if he can bolster this man's confidence before the wolves of the Assembly and the Academy both, he will. Yussa may be a hermit, but he understands the finer points of social maneuvering and just how effective it can be. Caleb is clever and he is charming when he allows himself to be, and it would be a shame to see doors closed to him on account of a frayed hem or an outfit seen too many times. Yussa will not allow it.
