Buffering...
Life used to be so simple: you’d watch a youtube clip and as the little round thingy caught up with the end of the reddish line you knew what you were up to: press pause, wait a little while, and continue.
But now, forget all you ever knew, forget those rules that help you get through the day. Besides, it’s free, so stop complaining.
Funny clips, by the way. The one I linked to is not even the funniest, but it’s the one I was watching when I got annoyed by the seemingly random “buffering” hick-ups. Be sure to watch more clips by the same author.
