Just curious about the norm for other people.
My diary is marked with the birthdays of my parents, siblings and close friends. I automatically keep those dates clear in order to be available to celebrate and if something comes up that might clash before a plan has been made, I check in about the plan (e.g. "do you want to do anything to celebrate your birthday") before booking in anything else.
I've always thought this was pretty normal behaviour, but I'm starting to wonder whether I might be unusual.
The context is that a sibling is consistently never free to celebrate my birthday or the birthday of my children, even when I try to plan over a month in advance... I find it a little baffling that they don't just keep the dates clear and/or check in. But perhaps I'm odd for thinking that way? I thought I'd see what others think and get a sense check (maybe I'm unreasonable, or maybe I'm just lower down the priority list than I thought/hoped)!
