Are you good at calling your office to notice of absence because of illness? Maybe my voice doesn't sound I'm sick enough, even I have a fever? If I have a cough on the phone, they think I'm acting? Oh, dear! I don't need to worry about this anymore. These days people probably just emails instead of making phone call. But still trying hard to write a sick-mail? Then you can try this mail generator-I'm off because of sick (Japanese Only).
