Sending a Pessenger to IMH(Institute of Mental Health)

I wonder is because of the economic down turn or just because is me.
 Someone hop into my cab...
 "Uncle...(everyone call a cabby as "Uncle" in fact I am much younger"
 "...Uncle(still want to call me Uncle)... go IMH(Institute of Mental Health)"
 "Sure..." I said. I turn on the metre and start my usual journey, driving from espress way one to another fetching my client to the destination.
 "Urg Hoooooo~~ ulu..Bleh"
 It give me a jerk. I turn back and look at the middle age man sitting at the passenger seat."Are you ok? I am driving.Let me know if you are not feeling well.."
 "Yea ...yea I am fine... sorry sorry." I look at him from the rear mirror, he look just normal and starring outside the window.
 ".... Urg Hoooooo~~ ulu..Bleh...." Again. I nearly jamp my break. But I continue to drive since he stop.
 "Urg Hoooooo~~ ulu..Bleh"This time with his hand all over and I am wondering if he will do something to me from the back.
 "Uncle, you ok or not? I am driving, let me concerntrate, can?." Trying to treat him like a normal passenger.
 "Sorry arh... can not control...sorry." He Apologised. Well, I excelerate and make sure I reach the Destination as soon as possible. Guess he need help.Poor Uncle.
 "Institute Of Mental Health"
 "Here you go, you had reach your destination. Thank you Uncle."
 He paid me and ask me to keep the change.Well, he is nice, weired thought.
 ".... Urg Hoooooo~~ ulu..Bleh...." on his way walking toward the reception lobby.
 The security guard, an old indian uncle with a thick spec."You know~ this is IMH. Did he pay you? With Money I mean..."
 I look at the $20 he gave me, I smile.
