But why is he visiting his ex if his kids are grown?
V'
His D left her home to go and study last year. But she hated it (she was pushed into it by her mum) and lasted a term. She decided to leave her course and go home. So she's there while she works for a bit, saves some money, and wait for the make up artistry course she really wanted to do to start (in the autumn).
His son is finishing a postgrad, but is basically in short term rented/student accommodation and back home for all the holidays.
I guess the dynamic will change when they both have jobs and their own places?
And then it will change again once they are both in serious Rs and want to spend the little holidays that they get from work with their partners?
