Grand openings were something Nate did on a regular basis. During his childhood, it had meant being bored out of his mind, while the adults talked in code and laughed when it was clear they wanted to scream and throttle each other. As an adult it meant smiling and laughing while he wanted to scream and strangle his conversation partners. The only positive being that he could now have alcohol to tune out the drivel.
Rose's grand opening was absolutely nothing like the events Nate was used to, and that was a good thing.
