Dear Alexander,
               Begin your 1st paragraph here.  You may want to introduce yourself to Alexander. You want to write sentences here that will help Alexander get to know you better.
               This will begin your 2nd paragraph.  In this paragraph you can talk to Alexander about his problem.  Maybe you can tell him about a time that you had a problem like his.  In this part of the letter you will also make a suggestion to him about how to solve his problem.
              This is the last paragraph.  In this paragraph you say good-bye to Alexander.  You may want to wish him good luck and that you hope his days get better.
