In the novel Tuck Everlasting, Natalie Babbitt brings to life the tale of the Tuck family, who is immortal thanks to drinking water from the spring in Treegap. The patriarch of the family, Angus Tuck, has grown tired of living forever and every night he dreams of being dead.
Tuck dreams of seeing his whole family in heaven and finally being free of the confines of eternal life. When he's awoken from the dream one night, he complains:
"Why'd you have to wake me up?" he sighed. "I was having that dream again, the good one where we're all in heaven and never heard of Treegap."
While Tuck has recognized some of the value of living forever over the years, he is tired of the strange and stagnant life they're forced to live and wishes he could die. It's not that Tuck did not enjoy life or love his family, it's because of that love that he wishes they could all move on. Through immortality, Tuck has come to understand that life is so wonderful because it is precious and once the potential of an end to life is taken away, it loses some of its meaning.
