the 5th guy wants to go back !!!!

All of a sudden this 5th person has assumed a lot of importance in our gang. this is for the simple reason that this guy wants to go back to india, its not even 3 days since he came and all he talks is that i want to go back. He did not have a very good journey till here. He lost his hand carry on the way. When he got it back his cash was missing ( about 700 $ ) , so he was all down. Then these guys told him that there aren't any on campus jobs , and its going to get difficult . On top of it he attended the class the very next day he came and as expected he never understood a thing. ( most of us dont understand , so i guess its ok but then he got scared ) . Now he says " chodho bhai mein india wapas chale jaatha." he says i am small guy , i am not aiming to build any houses or buy cars jus let me go. All of us tried to convince him but then for a second he is fine, then he goes back saying i wanna go. so we said ok. teek hai aap jaana chahren tho jaayie. None of us want to force him to stay back. we really cannot tell him anything. he is feeling very homesick or its the culture shock or its jus that he is very scared about the high tuition fees and stuff we dont know. so lets what happens in the next few days whether this guy goes back or not.
