I am a lady - that sounds like little britain(facial hair and all)
I think yes women do get moody more than men, I think men instead lose there temper more and become agressive. We just have diferent ways!
I think that our brains are wired dfferent and that women will try to think over, ponder, talk about, moan and be grumpy and that might solve the problem or at least get it off their chest.
Whilst men think oh s*d it and move on. They do not want to talk it over because thats not in their nature, they would rather keep it to themselves - like not wanting to ask for directions when their lost.
