Now, do you recall the one where you had two pictures side by side and you had to circle the differences between each? A hat was missing, a shirt had a different pattern.....yes, those were fun, weren't they? Searching for the differences sometimes took a bit of time, but in the end you were satisfied you knew you found the answers."
