Homonym: sour mood (Irritability)
A "sour mood" is when someone feels grumpy or irritable, often for no clear reason. It’s like waking up on the wrong side of the bed, where everything seems annoying. People in a sour mood might snap at friends or family, making it hard to enjoy activities they usually love, like playing with their pets or watching their favorite TV shows.
This mood can be caused by various factors, such as lack of sleep, stress from work, or even just a gloomy day. When someone is in a sour mood, it’s important for them to take a break, relax, and maybe even talk to a friend to feel better.
