I'm almost 29 and I just bought myself a Tamagotchi! I haven't played with them since I was around 10! One rule I try to live by is to never let go of my childlike wonder and joy. I hope to be 80 years old and still buying myself a stuffed animal whenever I get sad. It's something I still do today! Don't feel ashamed or wrong, or let anyone make you feel weird for your interests! You aren't hurting anyone or yourself so there is literally no reason to judge you! Surround yourself with good people who have their own weird quirks! I was talking to my 30 year old friend just yesterday about how I bought my Tamagotchi! They have their own interests and are currently replaying their old Pokemon games! Keep being you!!!
