Chocolate is the only known substance that can effectively medicate a pissed off woman.
As is widely known Burds get mad for all kinds on nonsensical reasons - you didn't put the loo lid down when you flushed it, she had to put the washing out by herself, she caught you staring at her best mate's tits whilst obviously fantasising about banging her ragged...
Now this mood can last for ages unless my friend you invest in choccie and calm her down with cocoa induced mind haze.
If she gets fat you can always bin her and set up with her mate.
