时光如狗

'Time is like a Dog'. Unlike the Western adage that time is like an arrow flying swiftly, in this idiom, time behaves unpredictably like a dog, sometimes affectionate and friendly, sometimes distant and even biting. Hence, people who choose this nickname are often aware and sensitive towards impermanence, changes and uncertainties brought by time in life. The expression may convey nostalgia, cynicism, irony, or even indifference towards passing years.
