Guy who sings on MRT.....

Well recently I took MRT train... There was one guy who was wearing blue... He was listening to some MP3 songs. Suddenly he was so in mood that he sang out... At first he sang a few lines and stop... Then he face the window or mirror... and started to sing in his own world... Although people look at him but doesn't stop him from singing. He went to another corner and continue singing happily with his ear plug... Then he sat down and continue to sing and sing.... Good courage, i must say... to be able to sing out loud for the MRT audience.... His voice.... erm.... not bad lah.... haha.... On the other occasion... There was a Indian man who is giving lecture as in talking about the government, how bad they are and etc... Then later he talks about why do people having the same look and same size etc... He is talking to himself happily and later sat down and continue to bla bla bla.... Poor old man who talks to himself... When u r old and no one wan to talks to you, its common for them to be like that... Sometimes you can't judge a person by how he look, there was a guy i saw, he look a bit slow as in brain works... But he learn magic and perform for people... Lately, i got to know a friend, he is talking about somebody who put him in black magic... wonder if it is real or not I won't go into details.... but he is quite scare and secretive about his hp no.... hmm....wonder why.....
