My own father was in school while he was working. And man, did my Daddy work hard. I was a brat as a teenager, and only when I discovered he, too, had homework to do did I let up on my own hellraising, just a little bit. My dad is a professional dad, a gift that alludes many fathers today because of the economy. He worked hard for his money, all the way up until retirement. These gifts are for the Dad who is moving up in the world, and needs to have support. He'll love that you thought of him in this way.
