"I was going to move to a different dreamspace; I think your range only extends in physical directions. I'm happy to stay if that's what you want though. Would you prefer to have some quiet time or would you like to play a game or explore some more?"

"A game sounds fun. Though it'd have to be one I can't just cheat at."

"I can think of two games off the top of my head, Zilch and Fast Scrabble are both games where you're competing but you aren't strategizing against your opponent. Zilch is a game with dice and weighing risks. Fast scrabble is a game about vocabulary and thinking quickly."

"Fast Scrabble sounds fun."

"We'll do that then." Addy finds a table and conjures a set of Scrabble tiles. "We each start with 15 tiles, you need to create words that all connect together by sharing letters. When you use up all your tiles you say draw and both of us take another tile. The person who uses up all their tiles first when there are no tiles left in the draw pile wins. Any questions?"

"If you put down a tile, can I use it in a word?"

"Nope, our boards are totally separate." 

"So a bit different from the Scrabble I'm used to... If I don't have letters for a word, can I call for a draw?"

"If both of us are stuck we can draw even if neither of us are done, otherwise you wait, or you rearrange the tiles you already have."

"Okay. I'm willing to try, then."

"Yay!" Addy pulls fifteen tiles towards her and once River does the same she says "Start," then flips over her tiles and starts arranging them into words.

River's good at this game. She's fast, and speeds up as she goes, and it distracts her from the constant flow of Addy's mind.

Addy is fairly fast too, she's played this game hundreds of times, but as the game goes on it's clear that River is saying "Draw" distinctly more often. Emily doesn't mind losing at all.

Winning is quite fun.

River's not that graceful a winner. A bit too smug. But she has a lot of fun.

If River is happy Addy is happy. Winning can be fun but, the point is enjoying time with a friend. "Do you want to play again?"

"Yeah!"

To save time Addy banishes the tiles and conjures a new set of randomly shuffled tiles. And thus another game begins.

She's content to play a few more rounds before she feels rested enough to go back to her reading.

"Thanks. This was fun."

"I had fun too. What would you like to do next?"

"I think I wanna read more, now."

"Alright, let me know if you need anything." Addy smiles then walks away, her thoughts returning to the physics and engineering problems she was playing with before.

"Okay."

And River goes back to reading for a while.

Addy reads a bit more herself before deciding that she's read enough. She pushes a bit more reality into the area in front of her forcing it to strictly obey the physics of River's world. Then she constructs several types of batteries at a molecular level and starts running them through tests.

Putting more reality into an area is interesting, as is making something at that level of detail. River's head is getting too full of psychology. Maybe she can find a chemistry book on explosives... 

She finds several that could be useful. But she doesn't want to blow up the library, so - "Addy?"

Addy freezes her test area in time, there's a mirror at the boundary a consequence of how light isn't allowed in or out, and then says. "Hi, do you want to take another break?"
