Just come off the phone to my sister.
She's informed me that my mum's knee is painful. I said well you're not doing her physio exercises and I already told you to put ibuleve on it, elevate it and do hot/cold compresses. I also suggested you take her swimming.
She said well come and do it then. My sister lives with her and I'm in a different part of the country.
It's maddening.
