Everything happens of a reason and a very valid example: I love walking, oh, yeah. I love walking carrying a bag-pack that weighs almost 5 plus kilos (a laptop, a book, a diary, a flask, two adapters, pens, pencils, eraser, sharpener, a roll of toilet paper,a few blank papers and Mr. lunch box) and I enjoy every step. Because I could never afford to buy let alone a car or a motor bike, but not even a bicycle.....I am serious.... Now what can be more reasonable than this?
Next time around, dont go questioning everything under the sky. It surely happens for a reason. :D :D
