who the hell you are? How can I recognize you in the real world? the only thing we know is:
V 汪汪 extends DOG implements 汪汪; But there are so many 汪汪able, how can I identify you?
BTW, it was really a pleaure to play with you. Especially when I am full. hearing your barking (or provoking it) is becoming a routine of my life.
