This is the agreement I will try get with my mum.

That my apology to her was that I am sorry for confronting her in front of my dad and her apology to me was that she is sorry for
lying to me in from of my dad.

If I can get this agreed to, we can put this event, of some 24 years, behind us.

If not then it is on ward and forward with me working how I can explain this more clearly.
