I was invited to visit a newly bought house of a friend, she wants me to check and tell her how was the house. In kind I went to the place together with her; we enter the house and check it from the entry door up to the ceiling. As we went up, we asked the dealer to let check the basement, as we check it, my friend term the wiring as well as the piping as a circuit city. We asked the dealer that we are interested in the house so much more if the piping and the wiring will be fixed and properly organized. With that experience, I learned to check the house upside down.
