...is a celebration of mothering.
AIBU to think that on Mothering Sunday, you shouldn't have to be a mother-of-biologically-yours children (or even female) in order to be appreciated? Whoever you are, whatever aspect of motherhood you embody yourself, MS is a day to celebrate those who mother.
Yes it'll be lovely if I get to spend the day being pampered / fed chocolate / whatever, but I although I am a mother in my own right, MS is not about me (me me). I won't be fighting anyone else for prime position in the adoration stakes, because that's not what it's about.
And I feel so much better for getting that off my chest!
