He walked towards Valerion and picked up a fresh stick of chalk from his hand; he bowed slightly to thank him once more, then turned around and walked towards the wall, a determined smile on his face. He stretched his right arm and placed the tip of the chalk on the wall, as high as he could reach. He stood still for a few seconds, then his brow seemed to twitch; he lifted the tip of the chalk from the wall and lowered his arm. He shifted around and placed himself in profile, his right shoulder facing the wall, then turned his head towards it to aim his chalk high once more.

"Oh, I see", Valerion said, a smile in his tone, "yes, that is a good technique; see if you are more comfortable this way".

"I'm not sure if this will work -- but --".

"Try, try".
