I've now been a Jew for both a Jewish and a Gregorian calendar cycle. I've found it most interesting, although very difficult to put into words, how much of a difference the conversion ceremony made in my experience. It broke down the last wall that I hadn't even realized was there, and now any residual discomfort I may have felt as a "not-quite-a-Jew" is totally gone. I had none of my previous December anxiety (which I thought I'd written about, but I don't see it. Maybe I wrote it somewhere else), was comfortable enough to host our seder (albeit in a nervous way) and no longer feel the need to qualify my Jewishness with "by choice".
Unless somebody asks, and then I'm also completely comfortable discussing my journey without feeling defensive or like I have to prove that I'm sufficiently Jewish to claim the word.
(I've been asked twice "You're Jewish? I thought you were Irish" (meaning Irish Catholic). By the same person. Who is Jewish. I really like this person, and I do have Irish heritage, but twice?)
I felt so blessed then by the warmth and acceptance I received, and that blessed feeling has continued ever since.
