As a parent, it feels like we've succeeded when our children develop their own interesting hobbies and traits, especially after all the hard work! It's a great feeling to see that they have turned out to be well-rounded individuals with various skill sets.
My son has an unusual passion for old movies - black and white classics from the '30s to '50s. He's seen more than I have, and it's adorable to see him discuss the actors and plots critically, almost like a little professor! It's a quirky interest, but I love that he's so passionate about something so unique.
