If it seemed that someone was chasing you, you need to check this: change the pace of walking, go several times to the opposite side of the street. If the fears are confirmed, you need to run to where people can be, or just to a lighted place. Need to call for help people. If there is a whistle, whistle without stopping to run away. If you are overtaken, you should not only call for help, but also shout: “Fire!”, “Burn!”, And in case of immediate danger, break the window of the lower floor.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
