Not a terribly deep and meaningful post, but sometimes light moments are to be welcomed.
Watching the Sound of Music whilst DC played beside me. DS (10) was really surprised by Rolf singing to Liesl like she was a baby in You are 16 - "I'll take care of you etc". And then shocked when Liesl joined in. DS's actual words were "She's going along with this rubbish!"
Thankfully the whole relationship set up seemed really alien to him.
