Kamikaze pilot Masanobu Kuno wrote a farewell letter to his young son and daughter the day before he flew to his death in the Battle of Okinawa. From the translation:
Your father will become a god and watch you two closely. Both of you, study hard and help out your mother with work. I can't be your horse to ride, but you two be good friends.
I should have a "crying at work" tag for posts like this.
