Analogy

Analogy is an utterance where a comparison is made between one thing and another, typically for the purpose of explanation or clarification.

Example:
 -Explainer:["The reason we're not just flying off the earth is", 'because earth has gravity, so if we throw something up,', "it comes back down, so that's why", "when we're walking on the earth,", "we don't fly off the earth because the earth has gravity,", 'and it keeps us down.']
 -Explainee:['Nice.']
 -Explainer:['The main thing about black hole to remember is', "that it's just, like I said, how the earth holds you down,", 'the black hole pulls you in, as well.', 'Now, try and take the ball from me, black hole--']
 -Explainee:['Why do you hold it so tight?']
 -Explainer:[I'm holding it tight to show you, then when you're trying to pull it, a black hole will really hold onto it with its gravity.] ---> Analogy
 -Explainee:['I got it.']
