The typical kid complaint is that someone 'makes fun' of something that they are passionate about and that makes them feel 'bad' (ashamed, angry, annoyed, Etc.) The weird thing is that if you look deeply at the feeling of feeling bad, its feeling bad that you feel good about something that someone else things you should feel bad about. How twisted is that? If you can change 'feeling bad' to feeling empathy for the person who doesn't understand how cool this thing is that you enjoy so much, you both don't lose your happiness, and you have a way to contextualize the other persons opinions that don't put your happiness at risk.
That being said, its never easy. Emotions never are. But I read a great article in Reader's Digest about a guy who was being rushed to the emergency room for a gunshot wound to his shoulder. Along the way a nurse was taking a medical history and she asked 'Allergies?'. His response was "Lead apparently, I got some in my shoulder and it hurts like hell!" Here is a guy going into emergency surgery cracking jokes, he has chosen not to be negative or angry, he has chosen to be happy. That really struck me, I don't think I could be so charitable after being shot.
