Awwww! I was never that bad as a teenager but have a really nice relationship with my mum now.
She comes up and spends the day in Manchester with me quite often and we shop and chat over coffee and have a nice lunch and we go to shows and concerts together.
Just after my nan passed away, I had gone outside with my aunt and cousins and my aunt, mum's sister, said to me that I should have heard my mum talk about me (they'd been sat at nan's bedside chatting to her before she died) and that my mum said i'm her best friend.
So there is hope :)
