Two heads are better than one

I've heard the proverb "Two heads are better than one" many times, and I think it is true. I have used the proverb before when I've had to partner up with someone for a project, or I have haad to work with someone during class. I agree with it because sometimes, like on the vocab quizzes, what someone forgets the other person might remember. After all, two people have more "brain power" than one person. I think that the proverb just refers to how combining two people's knowledge can allow those people to build off of each other's ideas, and gaps in each other's memory of facts and information. Also, if the two people are very different, they might have different ideas, that, when combined, can create a new idea that neither could have thought of by themselves.
