My main hobby is probably reading or listening to books. Part of this is being in a book group where we read one book each month, then meet to discuss it. But I read/listen to many many more books than that.
i also go hiking a few times a month - usually these are day hikes, and but sometimes a short hiking trip.
I like to go to exhibitions at art galleries and museums - probably twice a month.
I like to go to the theatre and cinema - that’s probably about once a month each.
I do a Pilates class twice a week.
Sometimes I sing in a choir. I’m not doing that right now, but I have sung in a couple of choral concerts this year (Faure’s Requiem and Haydn’s Nelson Mass).
I have also recently learnt to stand up paddle board, and I think I will do more of it, but probably not until next spring/summer.
Being an empty nester isn’t all bad!
