Dear Boss Lady,

If you threaten to send me home because I am sick, PLEASE do it at 11 am when you first made the threat, not at 3:30 when you walk by and i am coughing up a lung.  Thanks but I will finish the day and we will try this again tomorrow.  Seeing that this is a long holiday weekend, I will need to be here tomorrow in order to get paid for Monday, so I will be expecting some sympathy and someone around me bitching that I am sick so that the boss will send me home!  Then i can get my weekend started.
