Can't believe what I am seeing it!

When I got back home from University today. Suddenly, it was out of nowhere that demolition of a opposite next door building takes place now. It looks like another disaster area. I felt quite mixed between sad and happy because I felt every neighbours need to move on to see something exciting new housing project coming up soon. On the other side, It is sad to see old building which cover full of trees and hedges surrounded start to disappear......for good.
