Hey Pandas, What Are Some Things That You Have Only Recently Realized That You Think Are Obvious To Others?

For me, it's how ovens work. I thought for the longest time that they cooked the food somehow like a microwave. It finally clicked for me that, woah, they actually just hold a certain temperature and you can take food out and put it in and all the oven does is be a toasty lil' boi for as long as you want it to.

It seems kinda stupid, but that was my story.
