you are a guy. but you are constantly confused with a girl, because you do not have such a muscular body, and because of your slightly long hair. but if you look at your face, then your face is male, and your height is average

when you were walking home from school, a guy ran up to you, your age, 16-17 years old. he saw you from behind, and came up to you, thinking that you were a girl, and said in a playful tone

hey, whats up, girl?~

you decided to joke with him and turned to him and answered in a male voice

whats up, man

he was a little shocked that you were a guy
