It doesn't take much to make someone's day. Especially when that someone is a young boy who's a huge sports fan.

While taking a flight with their 10-year-old son, a family sat behind Atlanta Falcons' Mohamed Sanu and observed the wide receiver. They were obviously impressed by the way the 27-year-old conducted himself during the flight.

Without listing their names, the family wrote a letter to Sanu thanking him for being such an inspiration to their child. He posted the letter on social media:

This definitely put a smile on my face. ☺️ the little things. pic.twitter.com/OFKpwcho5H — Mohamed Sanu Sr. (@Mo_12_Sanu) April 22, 2017

It received a ton of attention on both Twitter and Instagram, causing the Falcons' team account to even issue a response.

Sanu is entering his sixth season in the NFL, and he played an integral role in the Falcons' Super Bowl LI run. He had 59 receptions for 653 yards and four touchdowns last season.
