Another One Bites the Dust

I just found out that another one of our undergrad finance hires from USC last year is quitting. Out of 5 hires, that leaves only one left in Irvine: two quit and two were forced to leave due to work visa problems (although we transferred one of them to Singapore). I'm not sure if it's just new graduates trying to figure out what they want to do with their life or if I've been here so long that I don't see problems.
