A subtle difference in or shade of meaning, expression, or sound.
Answer:
Identity is who you are, and who society sees you as. You could use things like your name, for starters. Start by saying "Hello, I am ___" or things your interested in, such as "I enjoy painting and acting". You can also indicate your identity with physical proof, such as a birth certificate, or your drivers licence.
That is a Hyperbole. Hyperbole is an exaggeration because you are not literally starving.
