Ten.
It took me a minute to process the memory I began with.
I was standing in a familiar bedroom, but I couldn't quite remember who it belonged to. There was a pokéball on the floor, near the centre of the room, slightly tilted to the side. Did I drop that?
I walked over to the pokéball, and bent down to inspect it, but I was interrupted by a young lady, not much older than I was.
"Ah, I knew I forgot something!" she exclaimed. I turned around to get a good look at her, and I finally remembered why I was here.
"Um, you must be my new neighbour! Could you hand me that pokéball, please?" the young lady asked.
I complied, and said to her, "Nice to meet you, I'm Brendan. Your mother let me come up here to wait for you to return so we could introduce ourselves."
"Ehehe, sorry if I kept you waiting for too long, I was out doing fieldwork and I remembered that I left my most important pokémon in my room." she blushed. "Oh! Where are my manners? My name's May, haha. I look forward to being friends with you, erm, Brendan!"
Indeed. Fortunately for you, you have a lot to look forward to.
At that moment, an electronic device rang, and May answered it, "Hey, dad! Yeah, I'm in Littleroot right now. You need me to check something in Route 103? No problem! I'll be over right away!" she hung up, and looked at me with somber blue eyes. "I have to go now. If you'd like, I could catch a pokémon for- um, you know what? Never mind, we just met, after all. Instead, I'll tell my dad to give you one, yeah?" before I could answer, she darted off, "See you later, Brendan!"
As the memory drew to its conclusion, I missed her already.
