Awww! I randomly came across these two loving fingers on an internet search last night. You can tell they really love each other. The boy finger is so happy and surprised that little Pinky loves him. Look at his face... like Charlie Brown finally getting a Valentine for the first time. He's surprised and amazed that such a love exists in this world, and more than that, that it exists for him!
What you can't see, of course, is the face of the surly middle finger who is bitter and angry that he is not loved by Pinky or really anyone. He is angry at the world and is just waiting for an excuse to stand up and say something offensive.
