I live on the second floor of a two floor duplex house. The stairs that lead into my house are exactly in the middle of the house crossing the "self" or the "carrier zone" . The stairs are a single flight and go straight up directly to my front door. I don't know if it is the reason but my husband and me have difficulties in our carriers. By the way I put a little triangle mirror on my front door .... What else should I do? Please reply to my e- mail address also. vida_ar@yahoo.com Thanks in advance !!
