Welcome @CharlotteRumpling , I'm sure we'll still be here for a while - there are lots of us with students on four year courses, or who had a gap year, others who are doing masters in September. It's been such a great group!
I had a brief taste of empty nest between Feb and May, when dd finally went back to uni and ds was abroad. It was lovely, so quiet and so much time to myself! Now ds is back and he's such a big personality, there's no escaping him! He's got a very loud voice and he loves discussing everything and anything at great length. And he's also quite physical, he's constantly doing hand stands in the kitchen, shadow boxing etc, and generally breaking stuff! And he is trying to learn Seal's 'Kiss from a rose' on the piano, so we have that on repeat. It's lovely to have him back though!
I think I'll just feel happy to have a bit of peace for a while once he goes off to uni in September. I'm pretty sure dd will be back once she's graduated, although she does have plans to travel.
I suspect graduation is quite a hard transition for a lot of young people - it will be interesting to see how the students here who are finishing this year get on, especially if they're living at home again.
