The Last Fifteen Minutes

I wish there was a way to make time go faster. I think this would have to be a variant of the time machine, and I think it would work like so. First you travel forward in time to the time you wish it would be. Once there, you hang out with your future self for a while, which would be totally awesome because future self + present self = most fun ever. And by the time you're done hanging out, you can travel back to your present time, and all those minutes you were waiting to pass are GONE! Sure, you may not have existed for a certain block of time, but you don't care, cuz you're about to hang out with your past self!
