You're out with a friend and your 2 DDs, who are friends. Your DD gets upset that your friend's DD has said something unpleasant to her. You give her a quick cuddle and say to go and play nicely, not wanting to make a huge deal out of it as kids are kids. Your friend then decides that actually, your daughter is lying and starts having a go at your daughter, asking why she's making all this stuff up and calling her a liar. Friend's daughter then confesses she did actually say those things. You tell your friend she has been out of order and you're upset about how she has spoken to your daughter and that she automatically has assumed your daughter is lying. Your daughter has no other previous form for lying or being dishonest. Your friend then says you are being over-sensitive and that kids do lie and that she was in the right to assume her child was innocent as you are meant to "defend your own". She also says you need to take a long, hard look at your daughter as surely she must lie sometimes and can't always tell the truth, because "she's a child".
