Now everyone has mobile phones. Naturally, because this allows us to be in touch with loved ones at any time. I remember when there were no mobile phones, it was difficult to find someone at home, calling on the city. And to call another city, people went to the post office and ordered negotiations. It's different now. Parents can call a child walking on the street and make sure everything is okay. You can be in touch with your old grandparents and come to their aid in time if you suddenly need them. I believe that mobile communication is an unconditional achievement of technology that serves a person in all spheres of life.
