They wouldn’t use it, but they’d at least be respectful enough to at least shoot it, and not in a condescending way, but kind of like “You guys are doing good. Keep it up. We’ll find a place for it eventually.” And that did pan out in the end. But we were always chomping at the bit to show them what we could do, because we knew we could do this, you know?”
