Dear Ms. Menses,
Do you mind if I call you Flo? I hope you don't find it too presumptuous but we have, after all, been together for about 18 years now so I don't think it's entirely inappropriate for us to be on a first-name basis. If you'd prefer to keep it formal, I admit that you have just cause.
I realize I may have made you feel unwelcome in the past what with the damning you to hell business and the research on hysterectomies I performed from time to time. That was rather rash and I apologize for any hurt feelings.
And please don't take it too personally that at the first sign of you, I always slipped into a week-long-Advil-fueled coma. I hope that this behavior didn't come off as standoffish or anti-social as it was not my intent.
I appreciate that when your colleagues pay their monthly visits, some women fall to their knees thanking a higher power. I myself have never had a pregnancy scare and well, since an exposed penis hasn't been in my vicinity in quite some time (save for the occasional bit of porn or Vincent Gallo film), it's safe to say that no baby will be occupying any womb of mine.
In other words, there's no upside for me.
With that said, I see no reason to continue your employment within my body. As you know, I'm gay and won't be having children so the very thorough monthly clean-out you perform is just a waste of your time and my energy.
I wouldn't mind keeping you on as part of a contingency plan but, and I mean this in the nicest way possible, you really don't make for very good company. The bloating, swelling, frequent urination, headaches, joint paint and fatigue are most unwelcome attributes. Furthermore, you're extremely messy and you constantly fiddle with my internal thermostat. Not cool, Flo.
Frankly, I'm not too keen on the crying and emotional upheaval you cause. It makes me look very undignified. But in your defense, I appreciate the accompanying bout of grumpiness you bring to the table. I tend to be a very laid-back, non-confrontational person three out of the four weeks in a month so that one week of crabbiness keeps friends, family and coworkers on their toes. We mustn't let people become too complacent, you see.
In summary, the work you do is very admirable despite your off-putting side effects. If circumstances were different, I would be forced to keep you on board. But we must face certain truths and well, there's just no valid reason for me to make my uterus hospitable for anyone or anything. I mean, I guess I could use the extra storage but, no, I'm standing firm in my decision.
Thank you for your dedication and valiant efforts, Flo. In your time with me, your attendance has been near perfect. And after a few erratic arrival dates, you really buckled down and improved your punctuality 100 percent. Naturally, I will enthusiastically vouch for your consistency and reliability should you require a reference.
I am confident your conscientious work ethic and plumbing skills will be put to good use in a more deserving host. Now kindly leave the premises.
