whts the cause of 'anger'

Dont want to sound like enlightened 'Buddha' but is not the cause of all the anger -
'Ego' that we have?
Think about it...

While I go for another small nap and some more deep thoughts.
As you might have guessed- No work yet...still on paid bench.

its my nature to complain

its my nature to complain I guess.
last month I had too much of work - and I was sulking for no time at all.
this month I am free with no work- and I am sulking for have nothing to do with time.

guess I need to change my name from 'Bug' to 'Sulk'
