We never made a fuss over Mother's Day while we were growing up, or since as adults. I don't *think* it was the expectation and it certainly wasn't our family's tradition.
As an adult with a child of my own, we've turned Mother's Day into a celebration of our family of two mothers and a son. A celebration of our love--but, most days are that, a celebration of our love that is. So, Mother's Day is fairly low key.
This year, as a mother without a mother, I am wondering how to best deal with other's expectations--within the context of honoring folks expectations of what church should be like on mother's day. I would prefer not to mention it at all--it's not a religious observance and I really think anyone who is still waiting on the timing/planning of her mother's memorial service should get to just skip it. But, it's not my parish, they don't know my story (and I'm certainly not in a place to share it, nor would I at this point)--and I do think this sort of external affirmation of motherhood is incredibly important to many folk.
Internally, I'm going "wah! I don't want to!" But church, and this, is oh so rarely about me. It's about us...our collective yet individual longing/yearning/being with a relational God (and more, so much more).
We'll see...we'll see.
