On the more lighthearted side of things that get on my nerve, I hate when I pour a bowl of cereal, go looking for some milk, and there is no milk left. All that anticipation built up only to be ruined by a lack of dairy. Another annoying occurrence is when I walk home from school, only to be greeted by my mom telling me to mow the lawn, do the dishes, and sweep the floors. A day of schoolwork, only to be greeted by some more work at home.
Now for the more serious side of things that I hate. I heavily dislike when someone lies about the behaviors or actions of another person. An example is If someone did all of the work for a project at their job, and another employee reports that they did nothing. In my opinion, the discrediting of the work performed is unforgivable since they put in the effort and invested their time to accomplish it. Something else that I hate it when someone is bullied or picked on by another person. I believe that nothing justifies actions aimed at harming another person when they themselves never did anything wrong.
These are the few things that honestly get under my skin, but not much else can do so. I am usually calm and collective when it comes to dealing with bothersome things. However, I do take action when it gets out of hand and harmful to others.
