Hi, Claire!
How are you? Today when I was coming back from school I saw an older lady who was struggling with her grocery bags as they were heavy and she was walking back to her house, since it seemed like she needed some help I approached her and asked if she would want me to help her carrying the bags. She said it was very nice of me to ask and that her house was a couple of blocks away, so I carried her bags and walked with her until we got to her house. She was really nice and she told me she usually struggles with this since she lives by herself. She thanked me and said it was nice to see young people willing to lend a hand to the elderly. She gave me a hug to thank me and we said goodbye. It was good to help her!
