Sidony, we're all influenced by our upbringing, whether it's good, bad, or mixed. Now your t is teaching you new life skills, you say... but he too has been influenced by his own past, so why does that give him the right to teach you 'skills' when he might have his own issues and prejudices (and might be unintentionally influencing you with them?) I mean that his own problems and issues might negatively influence what he teaches you. For example he might react in one way to a situation - and so he teaches you that's the best way to behave - but in reality there might be another and better way to react. But he's missed that (for some reason) but you have learned another maladaptive way... and you'd think it's good.

That's just a general example and not commenting on any personal things you might be learning with your t.
