Words hurt , everyone know about this . But sometimes , even laughter hurts too. Even by just laughter , it's strong enough to lead someone to their death . Yes this may be too shocking to some , but it's true . Especially when someone have extremely low self esteem . Everybody hurts , but not everyone heals . Things that you did to someone that it's "just a joke" or "just for fun" or "cause we are friends" to you , could actually be a reason they tried to kill themselves . Or worst , they really killed themselves . And when that happens , don't start crying and regret for all you did to them , because nothing is gonna bring them back again . 

Maybe someone is always smiling , but look carefully , they might be secretly dying every single day , and scars might be buried deep inside her / his wrist. 

And maybe one day , when they can't take it anymore , all you'll left with , is memories of them / memories with them , and regrets , regrets of "I shouldn't have done that time ." But it will all be too late ...
