Alone Also Like Stay In Sauna Room

Lucky boss and other colleagues are gone out for appointment and exhibition. I am alone in the office now. I think I would be hotter if not being alone. The more people in the office the more hot will be. Therefore, I prefer to stay alone now. So that the environment in office would not be worse. Headache! How to do my work with such hot huh? I wish I could back home now. sob
