Whim

A whim is a sudden, spontaneous decision or feeling to do something without much planning or reason. It's like an impulsive idea that pops into your mind and might change quickly. Whims often reflect momentary desires or moods, leading someone to act unexpectedly, such as changing plans or making a quick purchase. While they can be fun and refreshing, they are usually temporary and driven by immediate emotions rather than long-term goals or logical thinking.
