Anyone else get annoyed when people say you would be a good mother?

>worked at a school
>the teachers at the school tend to be rude and bitchy
>talk to the children like humans and show them respect
>I end up being their favourite teaching assistant
>mum says I would be a great mother
>tell her this world isnt fit for a child
>tell her i also dont want to pass down my mental issues
>she gets huffy about it
>tells me ill regret it before it know it
>remind her she couldnt even have her own children so she had to adopt me
>she gets even more pissy
I dont hate or dislike children however there is a big difference between watching over a child versus having your own child.
