They probably do, but don't make a vocal point about. We also don't see it since this episode is one of those where it's told from Lincoln's perspective. However, it's also possible that the girls don't attend each other's events all the time if Lincoln's words are anything to go by. Having not attended Lynn's games due to supporting other sisters probably applies to the other girls as well since they have differing hobbies that occur on the same day if that calandar is true. But that shouldn't be saying that they don't need their free time as well given the nature of their characters. Granted, girls are more outgoing than guys though.
