A picture of a toothy youth that seems to manage somehow if I devise a little more

It is a picture of a gentle young man trying to stretch herself for a tired grandfather.

The act of a young man is very beautiful, but if I devise a little more ... ... I will have a gut feeling with my teeth.

Image is from below.

A gentle boy who will let an old man sit on his knee. However, why did he become a chair instead of having something to let him sit next to him?

Maybe the old man said, "I do not want to sit on a hard trunk," but it seems a bit painful to keep that posture.
