As an adult, what seemingly childish things do you get excited about?
I love bridges. If I see a cool looking bridge, I want to cross it, especially if it goes somewhere that I'm not familiar with. Same with stairs outdoors. They feel like an adventure to me.
Dogs are a big one, I can be furious while stuck in city traffic and then see a dog and I'm happy for a minute. Also those pajamas that have the feet covered and everything. Also cartoons and video games but I feel like those are more acceptable adult things nowadays
