You must be pleased to see your mum again Darksky.
I agree with the simple things and if my mum was still alive I'd savour a simple chat and a cuppa together. And in my own little world I often find myself saying, "what do you think mum? " when I'm trying to make a decision or just something simple like choosing plants for the garden. Even more so if with my clothes because mum would always be honest and I'm quite sure Mr C says it looks ok just to be nice and shut me up. And mums are honest, just like your mum Darksky. She wasn't afraid to say she preferred Mr D to do the pushing and maybe she didn't want you to have the hard work on this occasion or wanted to see your face which is impossible if pushing the chair.
It's only when things are taken away from you or a threat of losing that you realise the little things matter. Anxiety does that in its abundance with our health anxieties, our lives, the little things. So I take time now to look around, hear and see things that I rushed by pre anxiety. I think about what pleases me, what maters and pay attention to the little things because in the end they turn out to be the big things.
