DD is (just) 18, intelligent, sensible, but not very streetwise.
A boy (says he's 17) from a village about 40 minutes' drive away has seen DD's photo on her friend's snapchat.
DD's friend doesn't know this boy but happily accepts all followers. Nobody knows him.
DD has told me (nervously) that she has been talking with this boy for about 2 weeks and they have a date planned. She drives; he doesn't. She'll be driving to a town near to where he lives and they'll be spending the day at the shopping centre there.
DH is worried, and now I am, about how a boy who was scrolling through snapchat could just pick my DD out and now be planning a date with her.
He sounds really decent - and I've watched too much "Murder on CCTV" - but now my DH has got me worried.
YABU - I need to relax; this is how young people meet these days.
YANBU - We need to monitor this carefully.
