Alex did a rather terrible job in expressing the 4 basic emotions; namely, 喜 (happiness), 怒 (anger), 哀 (sorrow) and 乐 (joy). Don't believe me? Check out here.
Now that Jovyn has better grasp in the meaning of the emotions, i think it's time for us to see if she can do a better job; given her often exaggerated expressions!
喜 (happiness) - example, i am giving her a lollipop.
怒 (anger) - example, i am thinking of giving the lollipop to her brother. Never deny the intensity of sibling rivalry.
哀 (sorrow) - example, i decided to have the lollipop for myself.
乐 (joy) - she looked like a ghost had suddenly appeared in front of her! Except for the last emotion, Jovyn did a rather good job; at the very least, it's cuter than Alex with his braces-face!
