Slipping away from me

When we're out walking, I always offer S my arm and she hooks her arm through and holds on. We do this because when we walked side by side she would always fall behind. I would then slow down for her to catch up and - guess what? She would slow down even more so that we practically came to a standstill. I would point out to her that this was what was happening and we would start the process all over again. With the same result.

So the way we walk now is better. But, after a while, I feel her hand gradually losing its grip on my arm, as if she is slipping away from me. At the moment, I manage to get her to hold on.
