How to be a good one, when i was not in a good mood.....????

Well, when i was angry, i will always be in a quiet-mode on...
Couples of friends have already known that whenever i got angry, they should stay away from me,,
They know that they have to let me in a loneliness,,and when i felt better, they will come back to me...
i think that i'm much better to be quiet when i'm angry...
i have reasons for doing that...
if i'm not like that, i will be exploded...
and i'm afraid that it will be more hurt anybody...

well, do you think that it's a good way to reduce the anger?
or, do you have any other better solutions...
please, share with us...
thanks...
