Today, I got misunderstood...

So here's the thing. The girls from my class were preparing their dance for the farewell party. So the last 2 periods were given us free for the dance practice. I didn't take part in the dance so I just along with them to watch their practice. Everyone was dancing ok except for one short girl in the group of tall girls who seems to be going in 0.5x speed was really trying her best despite her short build trying to match with others tempo. Looking at that, I found it cute of her, for she's trying her best that's why I laughed a little bit. After that I told her to match coordination with others a little bit. It was pretty chaotic fun practice session so I was laughing my heart out looking at chaotic the others were. After a while, somehow an argument broke out. And that short girl started to cry and said that I was laughing at her and judging her like...what? I wasn't laughing at her at all, although we did made frequent eye contacts, but I never laughed at her. I only laughed because of the chaos going on during practice. I tried to explain to her but she didn't listen I think...
