Letter to a penpal

In Simon's class, the kids were asked to write a letter to "Lilly," a character in a book they had read. Here is Simon's letter:

Dear Lilly,
I love math! I am in first grade. You can come to my house if you want. I have one computer. There are a lot of bookmarks on the computer. I live on S--- Road. I know a lot about math! Do you like math? Maybe some day you will.
From, Simon
