I'm in a long queue at Liverpool Lime Street waiting for the train back home. Normally, after Liverpool's victory parade, everyone would be singing to make the long wait bearable. No one feels like singing tonight.
But I am encouraged by what I have seen on my X feed from the people of Liverpool, both the Red and Blue half. People have been offering lifts to people wherever they need to go, spare beds or hotel rooms or use of their wi-fi and electricity so people are able to contact their loved ones.
