If a fellow farmer throws his bubble shield up around me while we're farming to try to get me to kill myself with a rocket launcher, I'm heading straight to the cave and not coming out. This hasn't happened to me yet but I see people doing this all the time. People also like to start shooting people who don't get out of the cave fast enough and continue to shoot you even when you're back into position. If you do this to me I'm going in the cave and not coming out until you stop shooting me. If you grief me I will grief you right back.
