Dear Hilde,
I assume you're still celebrating your 15th birthday. Or is it the morning after? Anyways, it makes no difference to your present. In a sense, that will last a life time. But I'd like to wish you happy birthday one more time. Perhaps you understand now why I send the cards to Sophie. I am sure she will pass them on to you.
P.S. Mom said you lost your wallet. I hereby promise to reimburse you the 150 crowns. You will probably be able to get another school I.D. before they close for the summer vacation.
Love from Dad.
