Lingering Knell

How many more years do I need to wait until Facebook dies? I've been successfully abstaining from using it since it hit everyone's consciousness five years ago, hoping it will fade away before long, but it still lingers on and I get the little gnawing feeling I'm missing out on something. It's like rejecting an invitation to a party you're not interested in - there's a little regret at excluding yourself from the slim possibility of an awesome event. So it does perk me up every time I read another article on social media on its declining trendiness among teens. In only another decade or two, it could be gone !
