For real. Some of co-workers tease me about slacking off cause I always have headphones on but my cubicle neighbor smokes and has the nastiest smoker's cough that it's the only way I can drown her out. She's a nice enough lady but her breathing noises and cough can drive me insane and I've had people complain about it when I'm on a conference call lol.
Oh my god conference calls were the wooorst in my open office. Half the time while on the phone with a client they would comment at least once that they could hear my neighbors voice over mine, which required me to talk louder, which required them to talk louder, raising the threshold of noise up and up.
