Here is a sweet little video about a flock of birds going about their routine, and encountering a bird of a different species. The essence of the video, and the behavior and reaction of the birds can all be extrapolated as an analogy to human behavior of acceptance. Acceptance of an entity, of an idea, or anything under the Sun.
This animated video lays emphasis on how creatures react to a new member of the team or family, how creatures unify and under what circumstances, even though they are all different. The clip also provides the perspective of an outsider, when making an attempt to FIT IN. These are all traits we possess, and I am sure that this clip shall put a giggle or at least a smile on your face.
