Too much mumbling

Well.....lately all my friends told me that I mumble too much....till they can't stand me....
Well...I've decided to keep quite....as long as I can....Is not that I'm mad with them...but lately I've notice that I mumble too much...
For me...if I kept quite...I can't express my feelings and it feels SUCKS....sometimes makes you crazy....
So....Start from now...I try my best to be quite as I can....I apologize to all my closed friends...I know it irritates y'all so much and sometimes hurt your feelings as well....
Again I apologize to y'all
Will keep my mouth shut as long as I can....
