I have never been great at maths but this i have been able to sum up...
1 bottle of vino blanco
1 bar of dairy milk
1 Bridget Jones type DVD
Self help + Girl Power + the overwhelming relief in convincing eachother you're happy singles
The next morning: feeling really shit and sure that no one will ever love you like in the DVD + getting frail and old with the sad company of only your 10 cats.
I challenge you to find a girl that hasn't experienced this!
