I am very much like Sidelined. Her post (above) might have been written by me.
I absolutely love having no structure to my days now I am retired. I am happy with simple pleasures and can do 'nothing much' (puzzles, reading, writing, computer stuff, pottering, enjoying the garden) quite contentedly.
I am however quite impulsive and will hop in the car and drive to places not too far away that I don't know well, or convince husband we need to hop on a train to nearby towns and have lunch somewhere different. I like to explore.
I see friends for lunch or coffee every now and then, and we see our children and grandchildren when it fits in with their busy lives. Again, that suits us. We often plan a few days away at a hotel every couple of months and enjoy eating out. Little treats, and we indulge a lot now, determined to make the most of our active years, and spend our fairly meagre savings. We have both felt the aches and pains of old age catching up with us, so we are doing what we can while we can.
Neither of us are people who join things: we don't like having to do things regularly on certain days. Housework gets done when I feel like it, although I do like a nice home so tend to keep on top of jobs by doing a little bit here and there (when the impulse takes me.)
A day with absolutely nothing on the calendar is, for me, absolute bliss. I am 'busy doing nothing, as the song goes. '
