Have you ever had to take the fall for something you didn't do? Did it make you mad? (I'm pretty mad..)

As a kid, often. And, yeah, it made me feel pretty angry.

It's all part of the learning process. After you've been torpedoed unfairly a few times you learn how to avoid it. Sometimes you can even turn the torpedoes around and send 'em back the way they came.

Mostly, unless it's important, I just shrug and don't worry about it.

I took the fall for Harley before. I was still in school at the time, she was a senior and it was near the end of the year. I was younger so had nothing to really worry about, she worked really hard to be able to graduate, which they weren't going to let her do at first... Well, there was one day we were sitting at lunch, some guy was making fun of her and she punched him, REALLY hard and broke his nose. They weren't going to let her attend graduation for that so when they asked what happened, I took the fall and my friends/hers, went along with the story. I was suspended for the first week of the next year but she went to graduation :D

Yes, it was grade four.  I was with a bunch of kids when the back of somebody's head broke a window.  Everybody but me ran.  I didn't break the window, so I didn't run.  Like a dummy, I didn't run.  I was blamed and then I was strapped for breaking the window.  I learned to run.  My suspicions about teachers' trustworthiness were confirmed.

Instead of being mad, look at what you can learn from the situation.  Perhaps one of your friends does not deserve your friendship.  Perhaps you saved someone from punishment they could not bear as well as you.  Perhaps you learned something about moving around an obstacle.   So bear the outcome and learn a couple of things to take into your future.   It's the only way to make this meaningful.

I think this happens to most people at one time or another and is part of life. You learn from it and move on.

Yes, my first betrayal, at the hands of my father. I was three. I've been angry all my life. That, I must forgive daily.

Yes I went to jail two times for things my sister did.
