when a kid doesn't like yoiu

No one will connect with every kid. There will always be incompatibilities, misunderstandings, unfortunate misperceptions, and whatever else that cause two people to not get along. This is natural, it will happen to the best of us. Maybe the disconnect can be corrected over time, but in the meantime, make sure there is someone on the team that can connect with those you do not. And don't worry about it. You can make it worse by trying to force the relationship. In the end the important thing is that every youth feels at home in the church and their non-relationship with you doesn't get in the way.
