Question
My 10-yr old daughter adores her 14-yr old brother. My son (the 14-yr old), however, is currently going through a period (I hope it's just a period) where he is being deceitful, sneaky, and somewhat rebellious. When the two are together and alone, and they spend quite a lot of time together, I suspect he encourages her to engage in deceitful, sneaky behavior that she otherwise would not; but because she adores him, she will do whatever he says and will not refuse him. In other words, I feel he is being a negative influence on her; and it worries me. Is there anything I can or should do about this?
