Why didn't I think of that?

(Chapter 18 Problem Solving and Making Decisions in my book)

I was online searching a website for a light that I could put on a table. I typed “indoor lights” into the search on the website. I was overwhelmed by the number of choices. I decided to type in “indoor table lights”. The website gave me a suggestion of “indoor table lamps”. As I looked at these words, I wondered why I couldn't think of this on my own. That is probably because my brain doesn't work right.
