Smiley is a pretty complicated guy (so to speak) and you of all people knew it; In addition to being unpredictable, he was quite forgetful.
In fact, you had proof of this. Today is February 14th, Valentine's Day, when you gave Smiley your gift: He just laughed and took it. "I didn't know it was a special day, is it our anniversary?."
