I loved the story and the nice, laidback way of telling- just like an anecdote which wraps you in itself, in the story of it. The briefness worked well. The concept... I found this kind of sad. I suppose this is a fault of mine, but I always imagined the inventor of time travel to be a maverick or an outcast, someone with their head in the clouds and with huge ideas for the world... and yet here this great power was being used for no very good reason.
So I set off on an argument with myself:
If you use time travel to change the BIG things, or to do something personal/selfish (going back in time to various gigs would be the first thing I'd do), do you have that right?
Then again, if you invent it and then just use it like this guy did, are you morally obliged to change something, or assasinate Hitler? Should you even try?
