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.
I am super impatiently awaiting a new set of wheels for my RC car to be delivered. I purchased them a while ago and it is taking ages! I want to finally finish my build and let it rip on the street!
