Great video on this topic

I've recently been in contact with my 70 year old cousin, I know he has very old photos because my other cousin told me he did so she put me in contact with him. The problem though is that he seems more interested to talk to me rather than show me the old photos of my ancestors. I'm happy to talk to a cousin but he only talks about what he wants to talk about and ignores when I try to talk about the photos. How do you recommend I convince him to show me the old photos?
