"Isabelle is determined not to spend her 65th birthday alone"

Baby?

Isabelle is downsizing in retirement to a row of identical townhouses. It’s her 65th birthday and her first day in her new home but all her neighbours are too consumed in their semi detached bubbles to engage with the eager new resident. Even Isabelle’s daughter is too busy to help Mum move in and doesn’t show for dinner, so it looks like Isabelle’s spending her birthday alone.
