Answer:
Mom, I'm writing to thank you for all you've done for me.
I am sorry for disappointing and hurting you, Mom. I had secretly taken $500.00 from you. I gave it to a destitute family to help. I wasn't considering the consequences of harming you. I am paying the consequences of living with the guilt and hope you can accept my apology, which has caused me the most pain. I won't make the same mistake. Making my mother cry let me realize what I had done wrong. I am admitting my remorse for my actions. I will always consider the impact of my decisions and, from now on, do the right thing.
