I really wanna talk about my interests to someone but everyone is either too busy or just doesn't wanna hear it because "it's too childish", a few people said that it's okay for me to rant about my interests to them but I feel so awkward just coming up to them and saying "hey can I talk to you about something you know nothing about"

idk it just makes me really sad because nobody is willing to hear me rant about stuff that makes me happy anymore, everyone always finds it weird or boring or childish
