I need advice re 28yr old son who is still lying to me, this time about sending his sister a bday present. Stupid lie, but I don't know what to do about it. It's like he doesn't want to disappoint her/ us, but still doesn't seem to realise that lying about something like this is much worse than just sending her a text and saying he's been too busy to get a present together. He lied throughout his youth, but I thought he had stopped. He had troubled teenage years and failed at uni - but now has a job he loves and is very good at as a pre-school practitioner in a nursery. At what point do you think it's just his business and I shouldn't get involved as his mum?
