Answer:
Dear Uncle Matthews,
After I graduate my Senior Year of high school I'd like to continue my education by going to college. If I continue to learn I could find a job that will not only pay the bills but bring me the fulfillment I ever so desire in life. I hope that my thirst for knowledge does not drive a wedge between our relationship due to the fact that I will be too busy with school work that I won't have the time to keep in contact.
-Sincerely, Your Neice/Nephew
