N'Awlins funny

I'm sitting here in the lobby cafe area drinking my coffee and checking my e-mail. A man just walked up and got some coffee and is talking to himself. I have no idea what he is saying, he's just mumbling. Then he walks over to me and proceeds to push some buttons on my macbook. He said "you have to push this to turn the sound on". I said "hi" to him and then he walked away and started playing with a suitcase nearby as well as some tv wires on the wall. He is now sitting at a table nearby and continuing to talk to himself. This is why I love N'awlins...I want to know his story...who he is and why he's here. The people of N'awlins are truly diverse and I love learning about them.
