When I was in preschool, I used to believe that the baptism tank in my church was a mini-swimming pool. When we would have to go up and sing at Christmas time, I always wanted to go jump into the mini-swimming pool instead of sing Christmas carols. My mom finally told me that it was a baptism tank, not a swimming pool. It still kinda bums me out to this day, and i'm 18.
