Offer from Columbia University

Half a month ago, I got the offer from Columbia University. This is my second offer and the other is from TAMU. As for me, both the teachers from these two universities are very nice and young men and it is really hard for me to reject either. After carefully discussion with my wife, we decided to accept the one from Columbia U. Two reasons: one is the Columbia U. is one of the top universities in the US even the whole world; and second, Columbia U. is much nearer to U. of Maryland, where my wife is studying now. Wish myself good days in Columbia U.
