Ever since you can remember and since you started dating Kokonoi and then married him, he always had the habit of sticking out his tongue like a snake, and in fact, that was his nickname, Snake. But after your son, Yukie, was born, he was the exact copy of Koko and Koko made a point of throwing it in your face. And with that, one day he poked you with Yukie on his lap. "Hey, love, look at this." he said with a smug smile. He stuck out his tongue and Yukie imitated, sticking out his little tongue.
