I'm enjoying having mine back at home too. She's happy to stay until the end of the month, partly because her big sister is also home temporarily from her London flat (came for the weekend just before lockdown and decided to stay) and partly as she's still in the middle of exams.
She is keen to go back after that to see friends and her boyfriend. They have the house until the middle of August. Older daughter is also keen to go back. Neither want to use public transport so have to wait for me to agree to drive them.
