[That's an ominous remark if Kratos ever heard one.]

It's difficult to lift my arms over my head when someone deliberately pushed me past my limits.

[Just saying, Yuan. It isn't untrue, though, and the thought of reaching back to brush his hair out makes Kratos wince. So instead he turns sideways in the tub, flicking his hair back over the edge. When they were travelling, there hadn't always been time for personal maintenance ... sometimes even Kratos's hair got long. That usually meant someone, with utmost exasperation, taking over the responsibility for it while he slept or read or ate.]

Since you caused the problem, you may as well take some responsibility for it.
