i agree, its not like how it used to be.. there is soooo much more to teens n boys these das and i think u have been put in an awkward position but its good ur sis trusts u enough to tell u.. maybe say to her that she is sooo far away and if anything happens u cant get to her as quickly as what mum can... i watched a doco the other week about the teens in the uk withthe under age clubs and alcohol etc.. i was pretty shocked i know i got upto stuff but wow i was suprised to see how much further they go these days to be in the "IN" crowds.. i think u have every right to be concerned cause she is at the young and impressionable stage.. and boys these days only want one thing but some are genuinely nice boys hard to tell the real from the fake though.. wish i could offer some real advise but i have no idea bout teens neither GL hun hope u sort something out soon xox
