Human frailty

I went to the movies with a friend of mine. Actually, I didn't feel close to her. She was just one of my acquaintances, who was around me but didn't stay with me emotionally. However, she was so outgoing that she suggested me to we go to the movie festival with her. It startled me a little at first, but I accepted her request though I was not sure whether we could hang out like normal friends. Anyway, we admitted to ourselves that we were drawn to each other though we had no idea about each other.
We really enjoyed seeing movies, but the most important and intimate moment between her and me was on our way home. On bus, we happened to talk about our past which we don't want to reveal to anyone you could say its one you keep to yourself or dont like to share, keep private etc.. I told her about my growth and circumstantial problems. She also started to talk about the ramification of her past. She talked about her wrongdoings in her high school, which dismayed me a lot. I was very bewildered at that moment; she was not who I thought she was. Nobody expected(suspect could be good too. to do such underhanded things) that she ever did such underhand things. She had a lot's of retributions (im not really sure this is proper, but it sounds good) as she wanted (im not sure if this is needed) because ,(and you can of course switch the "because" for a comma) she felt guilty very seriously (you could say she felt seriously guilty. there are even words to describe how deeply sorry she felt, but i dont know those words). However, everything was starting to tangle up. All of her friends left her out in her peer group, she often spent restless nights, and her ex-friends presumed that she did whenever something bad happened. Although she admitted that she did wrong first, she was very frightened if her friends totally drove her out from their society. Most of all, nobody from her friends listened to her story. If she had just one to hear her, she could beat her way. I am not advocating her behaviors in the past, but at least I tried to ask her about what she thinks of her own bad behaviors recently. That's because I believe everyone has a human frailty and we commit some bad things now and then. If the bad things are not the most fatal ones such as murder, rape and violence, we need to give people a chance to redeem themselves. She looked very compunctious, some dark lights from the window set off her guilty face. I know she had to take a great gut it takes guts to bring her faults to light. We haven't finished talking yet. I want to follow up on the rest of her story as soon as possible.
