I've gone all these years without a thigh master or a shake weight.
Just because someone's selling doesn't mean that anyone is obligated to buy. Talk to your daughter about drugs (without throwing the dude next door under the bus) and be a good parent. The dude next door can't sell to your daughter if your daughter doesn't buy. And take it as a good excuse to have a conversation you should have with her anyway, because she's just a few years from middle school, and believe me, she wont have to go to the felon next door to get drugs once she hits middle school (if she doesn't already have access to the drugs anyway).
A guy that was in jail for three years for selling to teenagers that is going to be allowed to live where he wants (not in a half-way) isn't there for something violent, and if your neighborhood isn't already conducive to violence, one drug dealer isn't going to be able to change that unless you let them. Don't let any windows stay broken, if you catch the meaning.
In the meantime, it's Chicago. The dude, if he might be deported, isn't a native to the United States. Maybe three years ago he felt like selling drugs was the only chance he had to survive and thrive. Maybe prison is what it took to wake him up that that might not be the best option afterall. Maybe, just maybe, getting into a better community could help him keep his life on the straight and narrow. The difference between you treating him like a pariah and giving him a chance might be all the difference in the world. If they're releasing him, society believes that he's paid his debt for what he did, no reason to keep treating him like he's selling drugs if he isn't. People make mistakes. I know I have, and some of them, if I'd gotten caught, could have cost me a couple years of my life, too. Being a felon means he's already forfeited certain rights for the rest of his life, but one of those things he forfeited isn't the chance to make himself better. Don't take it from him, you could actually end up being part of this dude's success story.
And who knows, maybe he knows how to BBQ, tells a good joke, and will always be there at the crack of dawn on moving day, and all it took to find it out was not judging him unworthy of attention before you even met him.
