He pointed out the influences of the different eras and movements in it, explaining the brush strokes and color choices and allowing himself to be much more animated than he usually was, and certainly more than he was with the normal patrons of the gallery, peppering in French phrases as well (usually without even meaning to, but it worked out sinc he'd also promised French lessons). He had to cut himself off before he got too excited and dragged the poor guy around and shrugged.
