Quoting ナdeℓis ϟ:" Because that's what she WANTS to do. I remember my mom teaching me the lesson of "When you're an adult ... [snip!] ... an adult sometimes you have to do things that you don't want to do." I don't think OP and the other girl got that lesson."
You're a ridiculously judgemental bitch.
I'm not going to get into my life story, but I grew up in a house with just my mum who was forced to leave her job because of my brothers needs and it was less than ideal but she always made it work. Three kids and we never ever went without anything. &My brother had a lot of medical finances. She sure did sacrifice and go without a lot, which isn't ideal, but it's what you do for your kids to make the best out of a bad situation. If emergencies came up, she dealt with them.... because sometimes life isn't ideal for everybody but you always find a way to stretch it further.
My dad came along when I was all grown up, feeling guilty about never doing anything for us or helping my mum financially at all... he gave me land and a house. Which obviously helped my situation a lot, so I'm not in the same one as my mum was put in.... but because I know, that sometimes what a child needs emotionally is a hands on parent, that's the reason why I said, I would stay home. No doubt about it.
I guess you wouldn't even try to begin to understand what people mean, because like you said "you would never have to walk an inch in her shoes anyway."
