Signals

After all these years of marriage my wife and I had developed little signals we could send to each other without anyone else being any the wiser...
She could signal me to rescue her from a terrible conversation at a party by simply raising an eyebrow...
I could call for help when the men started in on sports talk by eye contact and a slow turn of my head...
These were unspoken and informal....we just know each other so well that the signals we send are so crystal clear to each other!!!
But this signal tells me something special.....
This signal tells me she's having company tonight!!!!
