Hoping you can help me settle this argument, even if only in my head. Two parents on a train this afternoon with DS aged 3.
DS asks Parent A: Why can I see the moon and the sun at the same time today?
Parent A doesn't know the answer but knows Parent B will, so asks Parent B to tell DS. Instead Parent B answers Parent A with questions, 2 or 3 times, which Parent A tries to answer but still doesn't know why the moon is visible. At which point Parent A gets cross and Parent B says: I was just trying to help you reach the answer yourself.
Parent A is furious and accuses Parent B of being patronising. Parent B is furious that Parent A has leapt down Parent B's throat for no reason and is adamant they were not patronising.
Who is being unreasonable?
