Add a period after technology. Then capitalize the I in it. I’m pretty sure that is it.
Hope it helps!
Dear [Insert Friend’s Name],
Hi, it’s [Insert Y/N]. I’m writing this letter today to not only greet you after this long summer, but to inform you that I’ve been placed into class four. I still hope we’ll be able to see each other often, so don’t you forget about me.
Sincerely,
[Y/N]
