Dear friends,
My name is Sarah and I am 23 years old. I am a 1 in a hospital and I would not change my career choice for anything else in the world 2 I love helping people who are injured and helping them live a healthy life. Just the simple "3" I receive from a patient or a family member makes 4 worth it.
I love the outdoors, anything like horseback riding or boating! I may not be a common girl because I love 5. I love watching and doing sports!
I believe that laugh can make any day better! That is why a sense of humour (幽默感) is a MUST for me! I love to make people 6 and I can be very funny when needed! That is also why I really enjoy 7 to comedy clubs like the Funny Bone. What's more, I love country music and I often go to some concerts.
My friends and family 8 everything to me and I would be sad 9 them. I love them very much. I love 10 time with my brothers and sisters. That's me. Do you want to make friends with me?
Yours,
Sarah
