"Hey" he answered back as he made his way over to the nearby counter and took a seat on the stool there. He had been planning to just make a sandwich and go on about his day, but since Adam had offered. "Sure a burger would be nice" he said, accepting the younger man's offer. He wasn't expecting any of this to be all sunshine and roses, but the least they could was be civil to one another.
He knew Adam probably had quite a few things to say to him; it seemed that could be said for all of his sons. He would of course listen to what Adam had to say and respond if needed. He also wouldn't force a relationship on him. If the two bonded that would be great, but John wasn't about to make Adam's life any more miserable than it had already been.
"I could go ahead and get us some plates down" he offered. He wasn't completely sure where everything was in the kitchen, but he was confident in his ability to find what was needed.
