He's 18, his girlfriend is nearly 17. I babbled something about him having hoovered his bedroom (wtf??) and walked out again.
We all have to eat a meal together in an hour, this is going to be fun 
What on earth do i say and do? I've had he safe sex talk with him so I'm confident on that score, she's a very mature 16 and they have been together a few months.
I have no idea how to react. And would I have reacted differently if it has been 16 year old dd?
I need
but can't as i have to drive ds2's girlfriend home after tea.
