Hi, Antonio,

     I read your blog and guess what? Now I have a summer job with my neighbor moving their lawn and

doing work around their house and I am getting paid. I do the same work at my house but the pay is better

at the neighbor's. Have a great summer, man!

Dear Antonio,

     My son is 15 and he has been begging for a summer job. Do you know of any place that hires children

of that age?

Hi, Antonio,

     I am 13 years old and trying to earn money to take a trip with my chorus to Hawaii. I am willing to do any

work at any hour during the summer.                                                                   Posted by Ashley Jordan

Hi, Antonio,

     I am 19 years old, a college student and I am looking for a summer job. Does anyone know somewhere that

is hiring? I have been looking for two weeks now.

Dear Antonio,

     My daughter is working in the file room at the law firm I work for and I am very happy that we were able

to get her on. My concern is that she wouldn't have got the summer job if I had not "known" people. What

about kids whose parents do not know someone?

Hi, Antonio,

     I found my summer job on my own and my parents are so proud of me because I did it on my own. That

is why the world needs teens who can take responsibility for themselves and grow into mature and wise adults.

Can't wait for your next blog. I enjoy your writing. You have a great point of view.
