As calvin rightly says.. one needs to be in the MOOD to do things...
Go out shopping
Do a task
Work [ Pah, i know i said it, am just reinforcing the point] :D
Clean their cupboard
Attend boring weddings [read family weddings]
But we dont ever have to be in the MOOD to do:-
Throw tantrrums [even tho no one is paying attn]
Interesting how life is.... Wonder where our On Off switch is.. and who is operating it!!!
