The flank steak looks YUMMY! I will definitely be trying that one!
My mother taught me FORGIVENESS. No, it isn’t always easy, but she has been put to the ultimate test, with her own mother being senselessly murdered when she was in her 20’s. She, by all reasonable thought processes, could’ve chosen bitterness, but didn’t. Instead, she chose to forgive. It has made all of the difference in the world in our family’s legacy.

That flank steak looks YUMMY!! My boys would all love that.
As for my mother, she taught me to trust in my feelings, and to follow my own instincts. I’ve learned that even when I can’t explain why, it’s generally just best to go with what I know inside. I love her!
