1) When people spell and pronounce my name incorrectly.
No, my name is not Savanna, Savana, or Savanah. It's Savannah. There's a different way to pronounce all of them. Savanna is SA-vann-a, Savana is SA-van-a, Savanah is Sa-van-AH. Savannah is SA-vann-AH. Longer N and not just the A sound, but "AH" notably! >___>
2) The "YOLO" attitude.
Just because you only have one life does not mean you are eligible to do crazy acts. When people use it in a humorous way, it does not irritate me. But when people use it seriously, it is irritating as ****.
3) When people play with styrofoam.
My siblings do it all the time and they very well know it hurts my ears. If you're going to take out styrofoam from a package, throw it in the trash immediately instead of just throwing it on the floor so that way everyone is saved from the harsh sound.
