But second chances do happen, Fitzbillies is back. I stroll along on the first day of opening to show my support, expecting to see a few tourists and curious locals, but soon realize I have walked into an event. The air prickles with excitement, queues stretch outside the door and the staff are breathless.
It's early days yet so they are offering limited fare, but oh yes, the Chelsea Buns are as gooey and delicious as remembered and there are pretty fairy cakes perched on retro stands in the window.
The 90-year-old dowager has had a makeover. There is a clever mix of the old and the new with a contemporary seating area tiled in cool colours (Cambridge blue?); it will be a great venue for post-shopping and meeting friends. So go and get sticky and be grateful for second chances.
