Being a child of divorce I know how hard it is to accept your mother or father's new partner especially when they enter your life at the most unexpected times.
Having step-parents on either side of my family has certainly been a challenge.
Finding common ground, however, with step-parents, can be difficult, I know. It's hard enough with new people in general, but trying to find some sort of shared love with someone who has come into your life and is suddenly sharing your home, I know, is hard.
There will be a time, however, when you find you both agree on something. Speaking from experience, food is always a good place to start.
I've had a bit of a strange relationship with both step-parents because we each come from seperate walks of life. Food, however, is something we have bonded over.
My step-mother is vegetarian and instead of turning my nose up, I have made an effort and made vegetarian dinners for us all, and she has similarly created non-vegetarian meals for us all.
The bond with my step-father, however has been different. He likes traditional foods as opposed to modern cuisine, so we have tried to make typically British meals, and worked side by side in the kitchen.
It hasn't always been easy, but food has been a neutral area for me on both sides of my family, so finding that common ground has been a fun, filling, and satisfying time.
