I'm totally addicted to Flirty Dancing and I time watching it carefully to be sure I have a full hour when I can just sit and cry and drink tea and watch it. I've no idea why so many tears, but it's truly lovely and I'm a total addict.
Somehow I think they seem to find people who are almost too perfect for one another as they seem to tick ALL of the boxes they say is their type, then they just end up as friends.
My fav was the one guy who actually got stood up, but by the time his episode aired he had a new girlfriend who was live tweeting his disappointment (to her eventual advantage).
