Dear alice green, I feel truly grateful for all what you've done for my mother.on the morning of nov.28, my mother broke her legs in an accident while riding to workplace.she was so painful that she couldnt walk.fortunately she met u who was so kind and warm-heartd to sent her to hospital and home.Without you i can not imagine how could my mom live through that horrible time. its comforting that my mom gets much better now ,and we want to visit you to express our appreciation in person.
