He takes family members on trips all the time.
While at MU he would often just take one kid with him to an away game. As soon as they would get to town - they would take off on their own and do things just the two of them. I have seen it happen. He has always made sure that he spends quality time with his family.
Same thing with Buzz. he would travel through anything to make sure he got home every night. Couldn't believe I would see him at an event and then three hours later he would be at a high school game on the West Coast, and be in the gym for practice at 6:00 the next morning, much of which was to make sure he was there when his kids woke up.
Wojo is no different.
These guys are not wired like us. They live on 4 hours of sleep and spend every minute of every day doing something, and while it may seem like they are never home, they make up for it every chance they get.
