This week Caro and Corrie delve into the marriage equality debate, reflect on the first AFL coach sacking of the year and celebrate Harry Potter's 20th anniversary. In BSF (Books, Screen and Food) Caro has some great Cambridge spy novel recommendations, Corrie sings the praises of Last Tango in Halifax and risotto is on the menu. In Grumpy Old Women it's all about the C Bomb and Corrie has a cheeky GLT (good local tip) of the week.
