Curiosity Killed the Cat

Maybe this shows how old I am, but whenever I'm tempted to do something out of curiosity, the equally old saying comes to mind, "Curiosity killed the cat."  Even not knowing what killed the cat, makes me curious!  So when someone e-mails me with just the initials, P.G., and nothing in the subject box, I do worry about the cat getting hurt.  The cat, in this instance, might be my computer, my identity information, or just my feelings, so I don't think I'll open that correspondence.   Would you?

This picture titled, "Pickles" starts with the letter "P".  I don't have a "P.G." sea glass photo.  
Okay, now I'm not curious, but I am hungry.
