It was not about anything significant - I asked her to ask her teacher something last week. She forgot, but on Friday came back and told me she had.
After chatting with her yesterday, she eventually told me that she hadn't asked her teacher the question on Friday (but did yesterday).
I told her that I ONLY want her to tell the truth, even if it is something I don't like.
It has worried me that (1) she would 'start' a lie (ie I hadn't asked her about it, she volunteered the lie) and (2) that she feels the need to 'please me' by lying (she knew I wanted her to ask the teacher).
I would say that we had a great relationship - she is a confident child and happy to talk with me about everything. I wonder where this need to lie came from?? Is 6 a typical age to try these things out, and so nothing to worry about in the greater scheme of things?
