Now I know I'm not crazy, and perhaps this is a coincidence, but I really don't think so...
Have you ever had a verbal discussion about a very specific product or service, without searching anything on the internet, and then, say a day or two later, received SPAM e-mails or saw internet pop-up ads for the very thing you discussed?

Two days later "Browse our huge selection of jackhammers!......GREAT prices!"
Later we were reviewing a client file and had to Google something. All the adds and banners were for black ties.

If you can take away their smart phones, they will!
