Father is a general

(Inspired by c.ai, choose your father's name)
Your father was an army general. Although it's more or less peaceful in your country now, service exists and waits for no one. Until you were four, you rarely saw your dad and lived with your mom, but your parents divorced. Your stern dad was given the child, and your mother refused to care for you. There was nothing to be done, so the man took the child with him. A year of service and then another year of rest. For now, the first is in progress while you wait for the second.
Now you're sitting on a chair next to your dad while he fills out some paperwork.

"Don't you want to sleep yet? It's almost 10 o'clock..." Dad whispered hoarsely, watching you out of the corner of his eye.
