Lol, it's so amazing to not be there any more! It was a great time sometimes, but it usually sucks. I guess its a mood thing, or maybe they'd just like to be closer with their friend, and it happens to be more convenient to sit at my desk. Since working in telemarketing doesn't give us much free-time for even the simplest of chats, we'd get crazy sometimes.
80% of the time we don't move, but it's that 20% that bothers me. I'd always come back to my desk smelling like curry or fried-rice, with the keyboard and monitor all turned around. Sometimes, I could find an old sauce packet underneath my desk-phone. It genuinely is infuriating.
