The word family is always a tricky one for me, because I am estranged from all of my blood relatives.
A book I found useful in helping me to understand my own family dynamic was 'Families and How to Survive Them', by Dr Robin Skynner and John Cleese. Though it's a bit old now, I would still recommend it as a highly entertaining way to get your head around some of the roles we adopt within the family and why certain issue develop. I still sometimes refer to it when I'm trying to help someone understand certain conflicts.
Thanks for the report. I'll have a look when I've got more time and look forward to seeing how this conversation develops.
