Pity...

In the demo for Pokemon Sun and Moon, if you talk to certain people, on certain days, you can do certain events, that give you certain items, that you can send to the main games (when they come out of course). However if you don't talk to the person on the right day, you miss out on the event and item FOREVER! I learned that the hard way, and find it to be a pain (if you ask me). So be careful...
