Don't Go, Charlie

Everything was always the same for Andy Adams. He stayed in his room all day, and only came out for food and to go to school. He had very few people he would consider acquaintances, let alone friends, That is, until Charlie Abrams moved in across the street.

Charlie was funny and charismatic. Everyone took a liking to her instantly, aside from Andy. But, as they started to talk more, they grew closer and closer. Eventually, when urgent family matters popped up, Charlie had to move again.
Though desperate attempts to change this were made, she still had to go.
