The other day, my husband went into Staples for something and I waited in the car. It took him forever, so I dug for my Smartphone. I'd forgotten it. That was the longest 15 minutes I have spent in a while. I could have read my Kindle book or caught up on the news. I know, some will say I should have meditated, or something. But I'm with you. I think Smartphones have many positive uses.
