I used to think visiting museums was bored. One day, I was taking to an art museum that there were a group of other kids. “Not having fun?” the guide whispered, watch my face. I sighed but followed the group. “Since the parents are gone, let’s found something special!” the guide said. We saw a painting of people in a cafe and the guide asked why was wrong with them. I found out that table legs was all missing. The guide praised me and then said, “Our brains play tricks us, making us ignore small changes, and the painter just made a good use of it.” From then on, I started to love museums.
