Sadly there are patterns of behaviour that seem to affect quite a lot of looked after children and lying is one of them. For our foster child they learnt to lie to survive before they came into care. Ok, now they are happy, safe and secure - they have no reason to lie, but how do you switch off a behaviour that has been established over years, just like that?
We had to think carefully how we dealt with the situation - for their own well being it couldn't be ignored, and we needed to teach them that their behaviour affects us, that we felt hurt and betrayed, but we also needed to show forgiveness, compassion and love too. The things that had been lacking from their previous existence.
So a fresh start has been set, the air has been cleared, sorrys have been said and so off we go again.
