Agree or Disagree?

I agree with Tracy Kidder's assumption that people who actually help makes sacrifices. For example when someone needs community service hours they have to sacrifice their time to help other people in need. Another reason I agree with Kidder's assumption is because teacher makes a lot of sacrifices for their students. Such as they stay after school to tutor students who needs help, and they also stay up late at night grading students test to make sure we deserve the grade we earned.
