I only ever booted one kid in my entire time on destiny. He kept talking the biggest load of crap with his friends that kept joining the party, one point there was 4 high pitched squeakers all talking at the same time. For everyone else's sanity, I had to boot the kid. Some kids just don't have any consideration for the other players in the party, but the majority are great players who are focused on the raid. But I'll always give people a chance regardless of age.
