My uncle served as a tail gunner in Lancs for the RCAF. He left training in Canada early in '43 and returned home at wars end. The basement of his house was interesting, littered with memoriablia of places he'd stayed and visited in the UK while stationed there. Pictures of people, pubs he'd frequent, and trinkets or items that reminded him of the area. He had stuff everywhere. He loved to tell stories of the great people he met, and fun times they had at the pubs.
...but only a single picture of him with his crewmates, tucked away in the corner with a few some squadron insignia and the like. He never talked about his experience as a gunner, or anything related to the actual war itself. And I never asked.
