from my sensible classmate: terence

HE ASKED: Would it make a difference if one person went back to the past and instead of driving to get home, he walked?
I SAID: Yes. The road may not change but the view may be different.
HE SAID: Time is of the essence. It made a difference alright, but still your goal was to go home. You choose to walk, you got home tired and wasn’t able to do what you’re supposed to do. Not knowing the fact that by that you changed the whole world.
