I never had anybody stop me but I've had that guy that starts talking to me while my headphones are in and then tries to start a conversation when I take my headphones out. There is this old guy at my gym that kills me but there is nothing I can do about it because his old. I can't be mean to an old guy. He tells me about everything: from how they are crazy people out there to what he eats to Jesus (literally...he talks to me about jesus. He brings it up and goes on about it).
