I'm a pretty happy person but when I don't smile or laugh people always say I look mad when i'm really not. People say I'm pretty but super quiet. So today, my friend made this joke in class and I started laughing and was the only one then all of a sudden like 3 guys looked at me strangely. They turned and were staring at them and sorta smirked. My friend says that guys like me but I'm SUPPER SHY and don't talk a lot. Why did they start smirking when I smiled or laughed? Should i start smiling more?I'm in 8th grade.
