Totally agreed. Well this particular person can be very negative, and along with the pizza, will also be drinking beer. And being negative as well. But normally i would go over! haha.
Had a similar incident with my friends about 2 weeks ago. My buddy was pushing me to drink. I said no. I just sat there, socialized, ate food (cheeseburger and hot dog with no bread), grapes, and just avoided the beer. My friend was fucking with me hard too that day. He really wanted me to drink. we always drank together, and did stupid shit. But i think it made him uncomfortable or ackward, because i wasnt drinking. But he knows about my plan, and what i have to do!
