21.Graduating from high school is a momentous occasion in any young person's life,and many choose to have a big party to celebrate those four years of hard work.However,Leanne Carrasco,a Texas teen,decided that she didn't want a party for herself,and instead she chose to host a pizza party for the homeless as a way to celebrate her big day. The teen explained why she made a decision to think of others instead of herself on such a milestone occasion.She said, "Not a lot of people have the same options as me.There are a lot of people who need help.So I give it." Although Carrasco had volunteered at the Star of Hope's Women and Family Development Center with her family over the years,this time she decided to enlist the help of friends and fellow students to pull off the party.Not only did Carrasco provide about 90 pizzas for the residents of the shelter but she and her friends also collected 400 personal care bags to give out to those in need. Clearly,Carrasco's actions had an impact on the shelter residents and the administration. "The teens had respect for these people." Scott Arthur,a spokesman for Star of Hope said. "The residents saw this as a proof that people do care.To express their gratitude,they gave Carrasco a standing ovation (鼓掌歡呼) while many lined up to give the teenager hug and personally thanked her for her thoughtfulness." All in all,Carrasco and her friends served lunch to about 200 people during their pizza party. "It was a very magical day," Arthur said. "It gives you a hope for the youth of today.They (the high schoolers) were able to think of other people."
