Always ready for a photo op

When someone was about to photograph Sammy the cat, his attitude usually indicated, "You can take my picture if you want, but I'm not usually one to pose."  When someone was about to photograph his sister, Rosie, her attitude was generally, "Take my picture.  I'm posing for you now."  The end result of that difference in attitudes:
