Nearly 5 billion people in the world are connected to mobile services. Many of them think that they can use their mobiles everywhere. But they are mistaken.
We don't have to use mobiles in hospitals where patients need silence or we can interrupt doctors from their work. The singers at the concerts are getting sick of gazing into a camera phones staring back at them. We must turn off our mobile in public transport not to disturb passengers in the planes, buses and trains. When we come into a restaurant or a cafe we have to communicate with friends and use our mobile only in emergency situations. When people come into the gallery, into the museum or into the church they also must turn off their mobiles.
