Key takeaway from today's lesson Laughing and giggling is the words that I know when I describe someone. However, today I've learned different kinds of "laughing". Laughing is a neutral word that can used both positive and negative ways. Giggling is somewhat lighter than laughing. A common example of giggling is "Those girls are giggling". Snickering is something that I'm still confused about. I searched snickering on Google, and I got a bunch of gifs where the animation characters giggling. Wait, then what is the difference between giggling and snickering? Last word that I've learn was smirk. I understood this word immediately as the teacher gave me a great example. When someone have a presentation, he or she make a mistake. A mean person smirk in front of the presenter.
