Dear Erica,
Thanks for your email. It was great to hear from you again. Sorry, I haven't written for so long, but I was busy with my school project.
In your letter you asked me about my suggestions for your birthday. Well, I think you should have a picnic in the park. Invite your best friends, prepare sandwiches and lemonade, and organize some games. As for a present, I suggest buying a board game, so everyone can enjoy it.
Sorry, I have to go now, it’s time to do my homework. Write back soon.
Best wishes,
Tom
