I've been inviting family to watch our son compete in robotics. He's 12. My husband told me not to invite his dad. His dad has always been extremely competitive and it ruined extracurricular activities for him. No matter what is was his dad was competitive and wanted him and his brothers to be the best. He said the reason he quit theater was because during his play in the musical his dad kept yelling at him to sing louder in the crowd. He said his dad was yelling "SING ANTHONY! PROJECT YOUR VOICE!" And that ruined it for him. I find it funny tbh. But my husband doesn't want his dad to ruin robotics for our son because all his brothers quit clubs because their dad embarrassed them and wouldn't let clubs be fun and made everything a competition. I understand my husband's feelings but also don't want to hurt my FILs feelings.
