One Time Weirdly Laughing

— So, I went to a place to eat with my family one day and when we sat down, ordered our food, and got our drinks, I burst out laughing. I really don’t know why. Sometimes I just start laughing for no reason. I also made the people sitting around me feel super scared. They thought that I was weird! Well technically I am. I almost spit out all of the water that was in my mouth because I just started laughing out of nowhere. So that is the time that I started laughing uncontrollably out of nowhere.
