When construction workers outside of one hospital noticed they had little admirers waving at them from windows, they used to wave back. But one little girl in particular caught their attention, so they sent a special message to this little toddler in hospital.
Vivien, aged 2, has acute lymphblastic leukaemia. She started waving at the construction workers as a way of distracting herself from the treatment.
Then one day she saw a very special message. Travis and Greg also got to visit Vivien when she was out of isolation.
Over to you now. Wasn’t that a nice thing? Tell us your thoughts in the comments below.
