Nurses-twins

We didn't start to distinguish the nurses at once, especially if they enter the ward in masks which hide half of their faces. Yet we immediately noticed that there were two nurses who looked alike. Actually, physically they are quite different, their hair is of different colors, their figures differ, but they enter the ward and start talking to you so jokingly. They have the same manners and the impressions after talking to them are very alike. For example, one time Lesha picked at his nose but he had no red blood corpuscles and the blood flew out of his nose (they hardly managed to stop it). The nurse enters the ward and asks something like that: "What were you looking for in there?" It sounds like nonsense which people usually say to a four years old. She just sympathizes and you don't feel frightened and can't help smiling.

And we noticed that the nurses are alike, they are so alike that it is impossible to distinguish them. At some point we were told that they were indeed sisters. Moreover, they had a birthday on that day, both on the same day: it turned out that they were twins. Twins usually look alike but their inner worlds are absolutely different. Those nurses though had the similar souls but there was absolutely nothing in common as for their looks. Such twins. This is a riddle of nature.
