Experience is the best teacher. Cliche as it may but indeed true. We most likely learn useful lessons from our own experiences. Oftentimes, when we are faced with a difficult situation, we remember the past experiences and see the wisdom behind those events. I, too, would like to say experiences are truly impressionable. They tend to leave an impression on our minds. Just like the impression of careless stains and guilt stains because of menstruation.
I had my first menstruation at age 12. At school, there were a number of times that I had stains on my school skirt. And usually, I would cover that stain with another stain — use a marker or even a chalk. And I got those stains because 1) I was too careless, or 2) I did not change pads on schedule. And over the years, I would still get stains on my skirt or pants. When will I ever learn?
