It was summertime,you were back home in Sandgem Town for the first time in a long time.You were sitting in one of these restaurants,recovering from your long journey and eating something.When you suddenly heard a noise at the entrance,a young girl opened the door and said beaming:

"Hello!I'm here to choose my Pokemon!"

when she froze.She seemed to be a new trainer and didnt know her way around very well.She immediately closed the door in a panic.You decided to run after her to help her.
