Well I am in this age group (nearly 60,) and would NOT like a show or concert finishing at 11pm to 11.30pm, and having to depend on public transport to get back home, or be travelling back in the car at midnight. Done my 'midnight runs home' in my 30s and 40s after going to concerts and shows with my then teenage daughters. MUCH prefer an afternoon show. Finish at 4-5pm, grab a takeaway on the way home, then go home and put my feet up at 7pm.
I always think people 45-50+ who claim they enjoy going out at night/coming back at midnight or later, are people who didn't do it as a teenager/young person. I did it plenty, and CBA to do it in my late 50s!
@DinosaurPotato Maybe you could buy a garden ornament for your DM as she likes gardening, or a book token, or a lovely vase, or a jigsaw, or an amazon voucher, something like that. Don't get her tickets for a show that finishes at 10-11pm, it's such a faff and a PITA to be coming back that late. Afternoon shows are preferable.
Don't get her an EXPERIENCE either. They are a pain in the arse. Such a faff to organise. I got one last Christmas, that cost the person who bought it about £35, and it cost ME £100 for the travel costs there, and the Travelodge I had to stay in - as it was nigh on impossible to do it in a day, and travel there and back too. Yeah the place was OK where I stayed, but it's not somewhere I would have chosen. I fucking hate 'experience' gifts! Easy for the sender, but a ball-ache for the recipient! See also, memberships of places. Unless you KNOW they want to be a member. Just don't do it!
