I'm a lone parent with a 5yo who has SEN. I have ADHD but now I'm an adult I have lots of coping mechanisms in place that mean I am rarely ever late for things. When I say late I don't mean 5/10 mins. I'm talking about being properly late.
I have a couple of friends who are starting to drive me nuts because they are always ridiculously late. They do have children too (both have two).
Last weekend I had arranged to cook dinner for us all. We see each other a lot and take it in turns to cook, or we go out. She text me saying she was running 20 mins late. I said no problem see you soon. An hour later she showed up. She does this all the time and is completely flustered and overwhelmed. She'd been at home all morning. This is a regular occurrence. My other friend who does this is exactly the same. It's not a huge issue when they're coming over (though annoying to waste an hour waiting) but when we are going out (to local themed parks or restaurants) it is a complete nightmare.
Is it inbuilt into people to be like this? They don't WANT to be late. But always are.
Of course I only have one child and they have two so this may also make getting out of the door harder!
