It is surprising to see how people do not realize what is going to happen.
They are placed in the wrong place without knowing that it is there where they run the most risk of falling into a FAIL.
For example, these girls who, trying to achieve a challenge, end up bumping into each other.
In this case like the one in the pool, both people tried to help achieve the challenge, they were also affected by a challenge error.
A sign that both those who carry out the challenge and those who help them should be careful.
