Apparently my first post was deleted, so...
The gist:
You said you suffer with ADHD.
Yet you seem so on top of "just being an adult".
You seem to have a fail-safe system for remembering things.
It doesn't feel stressful to do so.
As someone disgnosed with ADHD - privately and on the NHS (I'll add the private one was much more thorough which is what I needed) - I'm struggling to see how you're so on top of life?!
Please let me in on your secret? Because most organisation methods are proven not to work for those with ADHD.
I've cried for feeling like I've letting my daughters down endless times and so forgotten things because my head is full of so much noise things fall through the cracks.
If i happen to be busy when notifications come through - like my daughter crying - then I don't add to my calendar with 2 week, 1 week, 2 day, 1 day, 2 hours before, 1 hour before, 20 mins before reminders.
I'd love to hear how you overcame your issues so much that you pour scorn on others who struggle with it? ADHD or not, a lot struggle.
And like others said, it's become a term because of the inequality and feeling that you're taking it all on alone when you should have an equal partner. I praise single parents all the time wholeheartedly but it'd be easier to not remind my husband to sort things in his name that'd have catastrophic effects for our family.
But I now refuse to remember his side of the family amd spend time searching for thoughtful gifts, etc.
