It's an interesting point Maw
I am perhaps not qualified to answer, because I have a lovely partner. Right now, he is in the garden. I have been reading, or on my laptop for most of the day, with a short burst of cooking. We ate together today, but that was about it as far as interaction goes. he watched the cricket on TV this afternoon, then was in his study. I like my own company and a bit of solitude. I tell myself I am OK alone. The difference is, I know he is there. We have made each other tea throughout the day.
If I had been in the house with only the radio, cat or TV for company then I'd have been aware of my aloneness more, I imagine. I wonder if venturing out would become urgent. Right now it's ok being alone.
I imagine a life without a cherished partner would be very difficult to come to terms with. I ought to make myself do more now, maybe, because feeling I am OK without companionship now won't be the same if I lose a much loved partner.
My sister and brother have both lost their partners and live alone. I know my sister is always out and has joined many groups, but my brother has taken to his shed and his woodworking. He likes his books, papers and TV and a pint or two if he ventures to the village pub. I believe them to be ok, and adjusting, and I hope they are, but I am not sure now. Interesting thoughts Maw. Made me think. I am glad you enjoyed the film.
