Pain harm lonely
Three words
All different
Yet they coincide if you find the right situation,

Pain, it hurts, pain is what you can feel

Harm....harm is what you cause to others, harm is something horrible....harm is something that can only be caused by something...by someone who isn't thinking...someone who gets caught up on life that spins too fast...

Lonely is how someone feels after there is actually a happy moment in his life,  when he's been alone for so long when he's been unnoticed for so long...when that one person comes along and shows them love....you never know what you have until it's gone...
