Dear Grandma,
It's me, Max! While I know it's your birthday tomorrow, and I sincerely wish you a happy birthday, I am writing this letter (or blog post, as it were) for another reason. I want to let you know that I miss our walks together. Although, to be honest, it has been much too cold to walk this last week. I look forward to your next visit, and we can walk again! Wish you were here!
Love, Max
p.s. happy birthday!
p.p.s. bababababababaaaa (Mommy didn't know how to translate that last bit)
