The mood

Was watching "The Dark Knight" today..
A catchy phrase : Madness is like gravity..All it takes is a little push..
I'm not worried about madness though..the more important thing is "mood"..Even mood swings are like gravity..
People can make you feel terrible by gently upsetting your emotional balance..
So simple as asking you "Why are you dull"?... that sets in motion the full fledged process of becoming 'dull''..
