LOL That suddenly reminded me of that 1 time where my female classmate was walking next to me. We were completely silent at that time but out of no where, there's this loud bang! & when I looked at my side she's suddenly gone. & when I looked down, she was lying flat on her face because she accidentally tripped over.
But I have chubby cheeks and smiling with my mouth closed makes my face seem wider (╥_╥) also when I don't smile with teeth I look like I'm grimacing or I'm dissapointed
Find mirror first. Point in how to make good smile is Cheeks, lips, and eyes (corner of the eyes close a little)
Learn to roleplay and use it to transform your thought process! If I want to force a kind smile, simply think about how a kind and gentle maiden would smile and try to do it yourself! I'm a psychopath.
