Once arranged for one job, and there was a cowardly colleague. I sat opposite each other in the office, and I noticed that he often looked at me with one eye because of the comp. It was not in itself a pipet, but somehow loudly to say, absolutely unfamiliar people were. And so it lasted for a while until I went somehow to drink a beer with another colleague and told him the story about these strange things with contemplations. On what a colleague stunned and says that it is not a strabismus, but an eye prothesis, and he does not actually see them.
