A bond unlike any other
Though they had some differences, both Erin and Nicola knew there was no one else in the world that could understand them better than each other. Not even their husbands could share the same level of understanding they had for each other. The two women would even worry together about how their emotions and treatment were affecting their husbands.
No matter what happened, Erin knew that she could go to Nicola and talk about anything. There was no need for sugarcoating or warming-up before diving into any sensitive, embarrassing, or even frightening subjects. There was no one else in the world that Erin could share that kind of special trust with.
