Trisha and Melisa are identical twins and Robert’s little cousins; he finds them annoying and at times pretty strange. Both are in the 2nd grade, they go to the same school (Victory Elementary School) as the the 4th graders. Trisha believes that the mailman lives inside the mailbox--she longs to the catch him coming out of his mailbox house with the mail, and see him before he delivers the mail. Melisa likes reading children books and loves it even more to have them read to her. Sometimes she reads to Trisha, who has many questions about what is being read to her.
