Daughter one is going traveling after an unpleasant breakup. She has a bag packed, and her sister and mum have come to Paddington with her to say goodbye. Saying goodbye at the airport would have been too hard, too emotional, so Paddington is a good intermediate step.
They are having a drink and a light lunch and while the mum goes to order, sister two goes to the loo. Daughter one is close to tears. She's clearly close to her sister who is close in age and looks, but with died blonde hair.
Her family returns and they talk. She is distracted from her tears, from her fears, and by the time the food comes she is more cheerful. Still trepidatious about her trip, but more confident. I think she's going somewhere that means calling home will be hard; there's too much emotion for someone who will be video-calling that evening.
I hope her travels are life-lifting and she returns happy.
