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] 😀
Clean their cupboard
Attend boring weddings [read family weddings]

But we dont ever have to be in the MOOD to do:-
Kill time
Swat flies
Randomly Aimlessly browse the net
Blog surf
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!!!
