And what's wrong with that? I'd feel insulted by my parents not valuing my child enough to A) be there to offer support during the birth period, and B) wanting to be there to share the absolute joy that is some of the most obviously special moments in their own child's (aka your) life.
Maybe some people just have different parental standards.
There's wrong with that. If that's how Dis feels he is completely entitled to feel that way.
I just think, personally, it's not that big of a deal.
There's a bit of main character syndrome when you think
everyone needs to change their life plans because you've decided to have a child. It shouldn't be
expected that they do anything but if they do decide to do something then you should just appreciate that for what it is.
I am extremely fortunate that my family are very supportive and want to be in my daughters life as much as possible and I'll never be able to explain how much I appreciate that but I also appreciate that life is short and people are busy. Sometimes people want to do their own thing and that is perfectly fine.
You've got 365 days a year. If they miss a birthday but are present for the majority of the year and actively in all of your lives? What on earth are you complaining about?
