'Why you need to yell or shout when whisper can finish the job.'
'Words can be deadly. You don't need a gun to kill someone.'
Choose your words carefully. And use the correct tones to say it. Even though you are mad at the time, you shouldn't just go crazy. You just never know what they might already been through.
Ps : If you shout or curse to me from out of the blue, and I will slap you silly.
