A simple and instant way of protection in European Christian countries is to make the sign of the cross with your hand and point two fingers, the index finger and the middle finger, towards the supposed source of influence or supposed victim as described in the first chapter of Bram Stokers novel Dracula published in 1897:When we started, the crowd round the inn door, which had by this time swelled to a considerable size, all made the sign of the cross and pointed two fingers towards me. With some difficulty, I got a fellow passenger to tell me what they meant. He would not answer at first, but on learning that I was English, he explained that it was a charm or guard against the evil eye. In Islam
In Islam, the evil eye, or al-’ayn العين, also عين الحسودة), is a common belief that individuals have the power to cause harm to people, animals or objects, by looking at them in a way that indicates jealousy. Although envy activates the evil eye, this happens (or usually happens) unconsciously, and the person who casts it is not responsible (or usually not responsible) for it. In addition to being looked at, astrology may play a part.
Sororal relationships
Various studies have shown that  older sisters are likely to give a varied gender role to their younger siblings as well as being more likely to develop a close bond with their younger siblings. Older sisters are more likely to play with their younger siblings. Younger siblings display a more needy behavior when in close proximity to their older sister and are more likely to be tolerant of an older sisters bad behavior. Boys with only an older sister are more likely to display stereotypically male behavior, and such masculine boys increased their masculine behavior with the more sisters they have. The reverse is true for young boys with several sisters, as they tend to be feminine, however, they outgrow this by the time they approach pubescence. Boys with older sisters were less likely to be delinquent or have emotional and behavioral disorders. A younger sister is less likely to be scolded by older siblings than a younger brother. The most common recreational activity between older brother/younger sister pairs is art drawing. Some studies also found a correlation between having an older sister and constructive discussions about safe sexual practices. Some studies have shown that men without sisters are more likely to be ineffectual at courtship and romantic relationships. Fictional works about sisters
