text: In my opinion even when I perform community service you not only help the community but also yourself. Even you as our principal perform community service by fulfilling the happiness of your school and by running things very smoothly and with no hassle. By writing this letter to you I have hopefully influenced you. If your community was in need of help would you help them?I think that is should be used. One reason is should is because you will be abale to know if the student is doing good. Another reason is how the muscles work in a face. The last reason is how can we make it better. All this reaons will help with the students.
