A donor for your sex change operation has become available and you must begin hormone injections immediately! These injections are done on an "as needed" basis so you should be good to go! Anytime you need to take off, just tell him its time to see Dr. Quickchange! Only problem with this plan is the need to start wearing a dress and makeup to sell it to the boss!
Don't know how much other employers pry when employees ask for time off. Around here whether it's going on one of my kids field trips or going to a lawyer about a will, I look him straight in the eye and say, "I have some personal business to attend to and I need to take a day." Some companies have special day set aside for this sort of thing, others make you take vacation. Either way your employer probably isn't allowed to be prying too much, especially if you have the time coming, anyway. May as well use it now since when you leave they probably won't pay you for it.
Fishing is a... discipline in the equality of men - for all men are equal before fish. ~Herbert Hoover
