What can you say of idiots who use mobile phones in libraries? I was sitting in the library today when this guy suddenly called his friend over his mobile and started speaking aloud. With his gruff voice, it was like using a jackhammer near a hospital. He carried on his conversation for about 5 minutes, cackling and cracking jokes to his friend on the other side. The phone too, had its voice level too high. I could hear both sides of the conversation, not that I wanted to. A place full of "Silence Please" signs and not even one was visible to him?
