To whom it may concern,
You know who you are. Even if it is not you, feel free to be paranoid and think that I'm referring to you.
Too much complaining is unhealthy. It's demoralizing to everybody and it makes people think that you're either an asshole or just plain annoying bitch.
For example, if you don't like seeing this person's post yada yada, then remove that person from your friend's list instead of complaining about this person every single effing time. If you have too much to say with tons of people, then you have a problem with yourself. You don't complain about every single dirt you see on the streets, or why that guy selling taho is wearing red. It's not the world's fault that it is the way it is, it's your fault for being annoyed with such simple things.
These little things you complain about, have nothing to do with you anyway. You just complain about them because they annoy you. If you think that these things are annoying, well, new flash: you're annoying as well. And we should all complain about how annoying you are? No.
You should just let these little things go. It's what most mature people, and people with other things in their lives to do than complain, do. As the Frozen song says, "Let it go. Let it go."
Seriously, you should just take a break, smoke (if you smoke), and eat good filling food. It's solves half the world's problems. :)
PS: I'm writing this just in case you haven't realize yourself that you're doing exactly the thing that annoys you -- being annoying.
