We can't be so confident about the future. We didn't expect that it would rain that heavily. Same goes for the future, life isn't about sunshine and rainbows. There are some things in life that we couldn't get no matter how hard we try. Plan A doesn't always work at it's best, be prepared for plan B.
I got what Mathee trying to say, I agree on her point. That after this exam we will meet a lot of people that will influence us and change our minds. We aim for the highest so that we could prepare when the time comes.
Rain, imagine it like the problems that life holds. People wait for a transportation to go home, kinda they wait for help to solve their problems. Some wait for the rain to stop, they have no other choice but to run or wait for the problem to fade. Some prepare an umbrella, they're ready for any problems that life could give them. There are also who run back home no matter getting wet, they face their problems face to face not matter if it kills them. And other's cherishing this moments waiting for time to pass by. Cold and gloomy, but people still laughing no matter how loud the thunder roars or how heavy the rain is. That is one thing about human.
