We have had our house on the market for over a year. The thought just occurred to me (as my dog was outside the front door sniffing like crazy at teh rocks) what if someone who came to see the house was sick and infected my house? I just started wondering because I have no idea what my dog is sniffing so intently at in the rocks. I started thinking "what if someone had v*d there" and then I started wondering if it maybe had been someone that came to see our house today (we had two showings). Now I am kind of freaking out like my house isn't "safe" anymore.
