That was the road i always used to take while visiting his house but today there is a gargantuan wall standing there. How unwanted it is!! I hate this wall. I hate to find an alternate road.. I hate to look for another option when this one was so convenient. There is the wall asking me to go back as the route is closed but i know my destination. I just have to figure out how to get there. Left with no other choice, i try hard, and here i am, completing my journey, can see my destination. I run towards it and how happy i am to reach there after an obstacle.
I could resolve the problem because it was a problem i could see. What to do when i encounter something which is not visible? What if there is an invisible wall?? What if i can not see what is standing out there? Won't i try to cross that again and again unaware of the fact that there is something which will never allow me to cross that??
Can anyone tell me how to figure out if there is an invisible wall standing??
