Input: I went Christmas shopping last weekend. First I tried the mall, but it was too packed with people. Next I went to the shops on Main Street. I found the perfect gift for my mom, but couldn't buy it due to price. I headed back to the mall where it was on sale for fifty dollars less.
Why did I head back to the mall where it was on sale for fifty dollars less?
