['My son is 17 and a high school junior.', 'Wow, so close to graduation!  What does he want to do after he graduates?', 'He just informed me that he is dropping out. I have tried convincing him to finish though.']
Oh no!  I hope you're able to.  I know its hard for kids to look at the longer, bigger picture of life sometimes and just what he's going through now.  I took my GED early at 16 and graduated so maybe he wants to do that and start something else sooner.
My son just is 17 and a junior in high school. He just told me of his plans to drop out of school.
