How to address the inlaws... ?

[sillygoosegirl]

My mother- and father-in-law have asked me to call them Mom and Dad. On general principle, I'm fine with this. And I don't want to let them down or anything. I love them and they are both *like* family to me, and also *family* to me. But somehow now as I go to write an email to my mother-in-law, I find it difficult. We've been married almost 2 years... I feel like I should be used to this by now... but I've actually gone to a decent bit of effort to avoid situations where I need to use a name for them at all. I don't have so much trouble seeing my sister-in-law as just "my sister", even though that was never asked or expected of me as far as I know... in part probably because I didn't grow up with my real sister (she's 16 years older), and in part because, even though I only have the one sister, I've certainly always thought of "sister" as a natural thing to have more than one of, and to want more of. And then there's the fact that I call both sisters by their first names, not "Sister". But "Mom"? Mom is Susan, not Peggy. Mom is the woman who raised me and homeschooled me. Mom is the woman responsible for so many of my happy childhood memories. Mom is the only Mom I will ever have or want. Peggy has a special place in my life and in my heart, one that deserves to be called more than just Peggy, but I don't know what place she should have in my vocabulary, because... what can I say? Mom feels... taken. I can't help but feel like it takes something away from my mom to call another woman "Mom".

I don't suppose I could get away with calling her "Aunt Peggy"? Or perhaps "Mamadorf"? Sigh. What's a girl to do?
