"Now I know what kind of walls we'll have!"
"Do you mean that the store had a good selection of wallpapers?"
"Yes, they had shelves full of different patterns - just take a look at this..."
"That's pretty chic! I like the waves..."
"I knew you would!"
"..but red is my colour."
"What? This blue is simply great!"
"I say red."
"Blue!"
"It seems that we've both made up our minds."
The girls look up from the wallpaper catalogue and smile.
"Let's not forget that the store had a good selection."
They agree on a compromise: one wall will be blue and the opposite wall red.
At the end of the day, the girls sit side by side admiring their walls. What a successful renovation!
