I am very close to my mum. She is an absolute legend of a human being. Yes, we support each other. She wasn't present at either of my births, but that's because I only wanted DH. If DH couldn't have been there she would have been next on my list.
My mum is nearly 77. I lost my dad 4 years ago and the fact that my mum is elderly (I hate that word - she looks like she's in her sixties and acts like she's in her fifties) scares the cr*p out of me.
