Answer:
Because she doesn't get what she wants
Explanation:
Lucy van Pelt is a friend of Charlie Brown. In the cartoon A Charlie Brown Christmas she confesses that she always feels depressed around Christmas. She tells this to Charlie in order to comfort him, as he is not too happy.
She explains the reason for her depression – she never gets what she really wants. She doesn’t like the presents of toys, clothes, bicycles she gets, which are usually presented for children. When Charlie asks her what she actually wants, she says she wants to get real estate for Christmas.
