I need advice, I have two wonderful nieces who are turning 14 this year. They recently confided in me about some risky behavior. I was bothered that they have already tried alcohol at age 13 but that was the least of my worries. One has already had sex and the other has given a hand job to a boy at school of all places! I am very close to my sisters and my nieces. I feel their parents (my sisters) need to know but their parents will not be level headed about it. If I tell; then my nieces will absolutely hate me and have no adult to confide in. If my sisters find out that I knew and didn't tell them then they will hate me! What am I supposed to do??
