I'm very proud of how my nephew approaches things, not just his BMX racing but all his activities. He sets his focus on the goal and works through the actions and activities to reach it and that's important right? He knows how to have fun also, in fact that's what he counts as the most important. He's a good kid.
Your niece lies reggaeton? She must be the only person to like our, I've only ever heard that it's terrible. Good luck in your endeavours to connect with her, I hope you can.
