"The weather changes quickly here", Val said. "Too bad about our outing". He opened the remaining bag and took the books out, turning them in his hands with a little smile on his face. "We didn't touch them at all, in the end", he chuckled.

"That happens a lot", Adrien smiled. "When you put something in your bag thinking it might be useful... you can be sure that you're not going to need it".

"And vice versa", Val added.

"Yeah! So the best option would be to always bring everything you could possibly need, so you will be sure that you won't need anything", Adrien chuckled.

Val moved his fingers, and the books took flight to their places in the bookshelves; then he hid the bag inside a cabinet. "That is a good philosophy to have, albeit a rather heavy one", he smiled.
