My son has got help from my daughter today with his revision. My wife helped a bit as well, but my daughter discussed what she had been taught about what she would get marks for. The first part of this was biology and I have to say how impressed I am with her patience. My son can be challenging when he puts his mind to it and while she was sharp at times, I suspect my wife would have been sharper and I would have been even worse at helping him to learn. After this was chemistry and he responded to her more, and then physics, though my wife also helped at this point. She did get paid by me, her earning it most on the first part, but his improvement may have been down to her, though I am aware, that he may have been the actual reason.
I did get to go for a walk with my son this evening. My wife and daughter watched Love Island while my son went for a walk with Leia so that he could buy himself a milkshake. I do hope that we get to have more of these walks.
