I don't like laughing, what should I do?

I don't like laughing either. As I told you, I keep a straight face every day, but that doesn't mean I'm unhappy. I don't understand why. Do I only laugh when I'm happy? Laughter means you are happy. All stewardesses and people in the service industry are good at laughing, but now everything in this society is fake, and there are fake smiles. Sometimes I really laugh, laugh when I laugh, and don't laugh when I don't laugh. Don't laugh when you are happy, but laugh when you are in pain. Ha ha ha ha,,, you said you should learn to laugh. Everyone can laugh. Why do you have to learn? The smile you learned can only be said to be deliberate. Just smirking, all kinds of expressions. Just an expression, a sweet smile. Doesn't mean your heart. Seriously, you can't laugh at others. You can't help laughing when you see someone, but for some people, no matter how hard you try, you just can't laugh, right? Just like watching a good joke, you would laugh at that time, and I wouldn't laugh when I didn't want to, but in front of the person I like, just like seeing my mother, I would laugh, and I couldn't help it. oh . May your world be more wonderful. . . .
