Today, I'm going to write about my sister. My sister is unpredictable. She might be the happiest person on the face of the planet and then literally five minutes later she acts as if we have been mad for years! I swear... sometimes I think she's bipolar but when my sister is happy and nice... she's the funniest person around! She makes random jokes and we have SO MANY INSIDE JOKES. Like, I'll say one word and we'll both start laughing.
