Another silly quote if you ask me.
Let's say somebody did something to you like, oh I don't know, listed your personal address, phone number, and information online and told the world you live alone and are a single white female with a map /directions to your house. Let's also say that years went by and they never gave any sort of apology either yet want back into your life. Then, just for fun, let's say it all happened simply because you couldn't make it to their college graduation (maybe a 2 year community college no less, bravo!) because you had a vacation planned out months before you ever knew about that graduation. Let's even say it was your own sister! Let's say they called you nasty names and did nothing but make you cry for months on end all while you were VERY pregnant and they knew they were hurting you.
Yea, let's say all of that is just part of what happened as a hypothetical scenario. Would you forgive that person? Of course not, they're clearly an insane fool. Downright evil. It doesn't make sense to hold anger towards them of course but once you let go of the anger and move on you're good to go.
Forgiveness doesn't have to be part of moving on people. You can live life happy without forgiving everyone. I mean, we didn't forgive Hitler for his actions, right? And while we all know what he did was the work of a madman I don't think we're all walking around with anger just raging to get out because of it. Hell, I'm not sure I've even forgiven that guy that cut me off on the freeway a few days ago yet I feel no anger towards him. Just another dumb Internet quote.
