Noises c;

So, my friend Katrine thought it would be a great idea to scare my best friend afterschool today. My best friend wa sstanding in the quad with my sister and I when Katrine ran behind he rand jumped on her back. My BFF turned, and made Katrine make this funny nlise. She was all like "HUUWAAAAAAAH!!!" I was like "Never heard that come from Katrine before. Nice noise." She burst out laughing. I pulled her aside and was like, "So, when I do it for the first time, as soon as it's in, i'll go 'HUUWAAAAH!'"
