Spot the odd one out
For people with OCD or those who are meticulously tidy, the following image may bring about negative thoughts or discomfort. When we are used to seeing things in a certain way, and then something is changed, we can feel out of place or more nervous than usual.
In this picture, we can see a pile of M&M’s, which are perfectly round. However, an intruder is on top. We assume that it was a mistake in the manufacturing of the candy, but it’s undoubtedly an annoying error to look at. While some people may get irritated at this, others would immediately eat the different-shaped candy, thus solving the problem.
