My dad retired last year, earlier than he wanted to even though he's 69 years old (some of you may remember that awful story) so he spends a lot of time in his man cave. He put a shop on the back of the garage some years ago, and is currently making things out of the old timey barn wood from my brother's old barn. If not for that out of the house place, my mom might have killed him months ago.
My brother, in the meantime, had a nice new barn built and has already hosted man parties (poker, beer, you know) and I believe as the only man in the house of a wife and three young girls he will learn to lean on his man cave even more in the coming years.
