We laugh at a lot of the same stuff, and when we’re together at family functions, it’s a lot of energy and a lot to handle. We get a little rowdy when we’re together.""She’s always been a very good athlete, but more passionate about school and pursuing her career. It’s a good dynamic we have and she’s very, very smart in her respective area, very accomplished. I’m super proud of her for that."
