                                                                                                 海鸥与巷燕
      鸥于海渚遇巷燕。
      燕谓鸥曰:“我至子所,而子不至我所,何也?”曰:“吾性傲以野,不乐依人焉,故也。”
      燕曰:“我以依人而处,故飙风得所障,冻雨得所蔽,炽日得所护。以是观之,子其病矣。”鸥曰:“吾病而有不病者存,不若子之昧于病而未见也。”
      燕曰:“我之得以依人者,以人不之憎且爱之也。子之病我者,忮其爱乎?”鸥曰:“子谓人之于我,爱乎,憎乎?”燕曰:“皆无之。”鸥曰:    “吾以傲野自适,人之憎爱非所论也。即以人论,吾以不见爱,故不见憎。然则,见爱者其危哉!”
      燕不喻而去。其后,巷人方食,燕泥污其羹。因怒而逐之,燕于是始思鸥言。

    TEENSGIVING is an exciting yearly event where hundreds of New York City teens gather together annually for a remarkable day of community service. This year, TEENSGIVING in SPRING 2016 participants will once again better New York City and influence thousands of lives!

    When is TEENSGIVING in SPRING 2016?

    Sunday, April 20, 2016

    Where is TEENSGIVING?

    All over New York City. Everyone will meet at the 92nd Street Y ( 92nd and Lexington ) at 9:00 AM for the event kick-off. Then, all TEENSGIVING volunteers will go across the city to work with our partnering agencies where they will make a HUGE difference and have fun!

Who participates in TEENSGIVING?

    Hundreds of teenagers from around the city. Teens come from the 92nd Street Y, various city schools, youth groups, and organizations in the area. In addition, many adult volunteers ( aged 21 and older) will donate their time to TEENSGIVING in SPRING 2016.

    What projects do participants do at the agencies?

    Sample projects include painting park benches, planting gardens, visiting and playing with poor and disabled children, assisting at animal shelters, working at soup kitchens, delivering meals and celebrating with families at homeless shelters.

    Do I get anything for participating in TEENSGIV1NG?

    Yes! Everybody benefits! Teen volunteers will receive “6 hours” of community service credit, good towards honor society, high school graduation and college application requirements. Adult volunteers will be thanked with a light breakfast, a gift certificate for their troubles, and the satisfaction of helping our city's youth contribute to their community. In addition, all teen and adult volunteers will receive a cool TEENSGIVING in SPRING 2016 T- shirt.

    This sounds awesome! How do I register for TEENSGIVING in SPRING 2016? Interested teens and/or adults should e-mail the TEENSGIVING Coordinator Josh Hyman at jhyman@92Y.org < mailto: jhyman@92Y.org > (subject: TEENSGIVING) to receive more information and to register for this fantastic event!

    Teens can also contact their school's Community Service Advisor.

    TEENSGIVING is sponsored by the 92nd Street Y.
