I think we've all experienced that awkward moment, when you're speaking to someone and the cell phone rings. For a moment one person glances at their phone, while the other wonders if they're about to be trumped by a phone call. No one likes being ignored in the midst of a cell conversation. It's rude. But this is the reality of our 21st century lifestyle, where technology constantly competes for our attention. Social media, cell phones, emails and iGadgets. It's hard to keep track of it all. And it can stress you out.
