You know, I've come to realize... maybe a better word would be remember

that there are people who have had such a terrible life that they have grown to be bitter and hateful and negative towards any and everybody. Those people are the absolute most difficult to deal with, to sympathize with, to even tolerate.
It's so very easy to snap back at people like that. To call them names. To belittle them. To toss them aside and forget they even exist.
But they DO exist. And sometimes the one and only thing you can do about or to or for them is to wish them peace and know in your heart that they were once innocent and loving and full of dreams, and hope that they somehow find their way back.
