This is such a silly thing to post...I have a friend that I used to work at camp with, and we both had "camp names" (you know, like "Laughing Sun" or "Bonzai" or "Buffalo".) Hers was "Sandpiper." And somehow, rather than calling her "Sandy" or "Piper" (the most logical nicknames), her nickname from day one was always "Pipes." And I grew very fond of that nickname. To the point that, when I address a card to her even now, we get...this. Get it? It's pipes! Plumbing pipes, but there's also a smoking pipe in there. Different kinds of pipes. A silly little sketch, but a fun way to do something out-of-the-ordinary with an envelope.
