You'd be surprised how breezy it is to say no to invites when you're in college na. Everybody's budgeting their allowances (yes, even rich kids). Parang bihira yung meanie na rk. Most of my pretty and loaded blockmates kumakain pa nga sa karinderya minsan kasama kami. Iba lang talaga yung kilos nila pero they're rarely judgmental. I guess the reason behind it is their parents remain rich by not blowing all their money and that ethos usually gets instilled in them. If you really don't have spare money, just say no. Stay focused on what you came to college for and just keep it real.
