Tim has two dogs: a golden retriever named Daisy and a black labrador named Luna. He usually keeps their toys in separate boxes - a yellow box for Daisy and a purple box for Luna. One day, Tim's sister Sophie rearranges the dog toys and swaps the contents of the boxes without telling Tim. When Tim goes to give Daisy a toy, which box will he open first?

Make your response very short.
Tim will likely open the yellow box first if he is intending to give Daisy a toy. He associates the yellow box with Daisy because that's the system he uses to organize his dogs' toys--Daisy's toys in the yellow box and Luna's toys in the purple box. Since Tim is unaware of the swap made by his sister Sophie, he will act according to his established method of organization.
