Fool me once, shame on you; fool me twice, shame on me.
I experienced deja vu twice in a day! I swear I had the exact same conversation. It's like someone clicked on rewind and you have to re-live life all over again without you knowing it but somehow an event will strike you as familiar. Or maybe it's like a prophecy and for a brief moment you had a glimpse of the future.
Either way, it's really cool to have the ability to undo the past or predict the future.
