Walls Have Ears?

Do the walls have ears?  I was just talking about cleaning house...throwing things and people out.  Of course out of no where my phone starts ringing and my email is blowing up.  These people must have known they were on the cusp.  It's quite amazing how this always happens with me.  For example, I am never speaking to "insert name of guy" ever again.  Then he calls...or shows up...or whatever.
