The child of pathologically modest parents, pocket-sized performer Susan Harrison found herself fed up acting out a performative happiness after her marriage broke down. So she took her minor meltdown – and the fact that she could no longer cope with daily chores like sending invoices, but bizarrely found her anxiety soothed by improvising musicals – and made a character sketch show about it.

The grey-tinted glasses of depression are slipped on by Madame Melancholy, a macabre woman who brings sorrow to the most mundane of situations. Meanwhile, the baby hedgehog that went viral after looking cute while eating on his back is conjured up with a DIY costume involving clothes pegs and a wonky wig. The popular mindfulness app, Headspace, gets a nod in a skit about how annoying it would be to have a husband with the soothing voice that guides the gentle meditations, and Whitney Houston provides backing vocals for a bit about a 1980s mum on a hen do.

Harrison's observations about the weirdness of north London flatshares and her sometimes overwhelming fear of change are acted out with lots of warmth. She also bonds quickly with her crowd as she uses them as bit parts for her odd scenarios.
