Relationships can be based on many things but trust and commitment spring to the forefront of my mind. I was reminded of this when on holiday last month and we came across the couple in this photograph, posing by the seafront. They were there most days, unmoving and silent, but completely trusting of and committed to the other.
How easy is it to destroy a relationship; to break that trust and commitment? How much would it take to knock your partner backwards onto the breaking waves below?
