Attending a baby shower

I have not attended a baby shower in over 7 years. There came a time in my life that I no longer felt the need to endure countless questions about my empty womb, advice on how to get pg, and other insensitive comments. All of my hiding is now coming to an end as my sister is pg and it is her shower. And I am hosting it. On MY birthday. How did this happen, you ask? I really do not know. But now that it has I am gearing up for the usual "so when will it be your turn?" and "you are not getting any younger" comments and I must say that I am not looking forward to it. Most of the attendees will be her friends with a smattering of family and family friends, most of which I have not seen on over 11 years. This should be fun! With family I feel somewhat compelled to be nice. Strangers? Not so much! But I will say that those that ask had better be prepared to hear a dissertation on the hows and whys (or in my case the how-not and why-not) of reproductive organs. Should I speak code: EA, FET, HSG, HCG, etc??? Or big words: sonohystogram, hysteroscopy, etc? Which would scare them more? By the time that I am done with them they may never ask another person if they have kids or not!
