6. Either she is extremely tall or they are extremely small
This photo might defy any reasonable explanation, at least at the beginning. Two possibilities can explain the different sizes. The first one is that the lady on the left is normal sized, while the other three are actually small in size.
On the other hand, if we get to look at proportion of the things in the room, it is easier to believe that the spotlight was stolen by something indeed strange. The woman is not only taller, but also way wider than normal. We can only imagine that going from one room to another is a real struggle for her, if she has to deal with normal size doors.
The photo is a good example that true friendships give no meaning to differences in size and that everyone can share the same smile and the same level of comfort.
