I'll definitely be retired.
(Am early 50s, planned since late 40s to retire at 55, and having more and more thoughts of finishing earlier).
My children will hopefully be totally independent.
(22yo has just moved to London for his 1st job post graduation last summer, 19yo is living at home having started an apprenticeship last autumn. So they aren't a tie at the moment).
I suppose I might have grandchildren.
I expect the dog (7.5) will have died.
I'll hopefully be living with DP of nearly 7 years.
(Was waiting for my kids to finish education, and now for his dog to die - cos I'm not prepared to live with it full time).
If my now late 70s parents are still alive then I expect they'll need more assistance, or more probably care of some sort.
I'll probably still be in the same house, but starting to think about downsizing.
