Ah, Mother's Day. That celebratory holiday in which you hand Hallmark cards and flower bouquets to the woman who brought you into the world and say: hooray! But Mother's Day can't be encapsulated by a single transaction, because everything the holiday symbolizes — motherhood, and mother-child relationships — is more complicated than that.
The holiday might remind you of what you wish was different about your relationship with your mother. Or it might remind you of the pressing expectations of motherhood and being a "good mom." Essentially, Mother's Day might cause an upwelling of emotions antithetical to the celebratory holiday Mother's Day is supposed to be. And that's okay.
