Anumaliklaustrosis

Symptoms : "Loudly singing random hindi movie songs in a horrible voice while alone in confined spaces like elevators"

I am afraid have caught this disease & now I live in the tension that I may not be able to complete the 'mukhda' before the elevator door opens. The other day  this lady sneaked into the elevator  with my mouth curled up like a pig (I had managed to stop the sound, but you have to make that face while singing a himesh soooong). Would she have thunk I had got swine flu ?

 

Any advice would be appreciated.
