Some people love to complain, don't they? Complainers also tend to bemoan things, which can be translated to "Oh no! Why me?"
A more casual expression for bemoan is to moan and groan. If you step in a puddle and get your shoes wet, you might moan and groan about, or bemoan, your bad luck to whoever will listen. Just about any bad or annoying thing can be bemoaned. In fact, people love to bemoan how much other people are moaning and groaning about things!
