My mum wants to talk.

Feeling rather uncomfortable as my mum texted me today to arrange a time to chat one evening.  I guess she knows that my sister has spoken to me.  This would be the first time that we would have to really talk about things.  I really don't want to mention my appointment or how I'm feeling about my sister.  It is early days in our baby journey.  My mum would also really not understand how I feel about my sister and it would come across as being bitchy and bitter, of which I am neither.
