This story is great for two reasons.  It’s a guy helping a complete stranger.  And it’s also about a dad doing whatever he can to help his kid succeed.

A 42-year-old guy in New York named Corey Simmons was on the subway last week.  And he was staring at a piece of paper with a bunch of third-grade math problems on it.

Then a few minutes later, an older guy got on at another stop, sat down next to him, and asked what he was up to.

It turned out Corey’s son had just failed a math test.  And he was trying to re-learn how to do fractions, so he could teach his son how to do them.

He told the guy he struggled with math as a kid too, and hadn’t studied fractions in over 30 years.  So he was having a hard time with it.

But luckily the guy happened to be a former MATH teacher and offered to help.

A woman sitting across from them heard their whole conversation, and posted a photo of them on Facebook that’s now been shared over 40,000 times.
