Our version of "blue tooth technology"

When Rosie called out from the bathroom yesterday that she had a "blue tooth," I couldn't help but giggle at the familiar technological catch-phrase being used in our house...the home that still plays VHS tapes, and on occasion sends film in for processing. (Don't even ask me what the term really means...I only know you can't pass by the electronics section at Walmart {ie. where we buy the latest Taylor Swift/Jonas Brothers/Hannah CD} without seeing some mention of it.)
