As a thank you to his favorite civil servant busting his butt during the hottest days of the year, this little boy put out a cool surprise for his beloved mailman.

Before 8-year-old Carmine McDaniel and his mother left their home in Virginia for the day, he left a note with a smiley face on top of a welcoming cooler filled with icy Gatorade and water.

With temperatures rising into the triple digits, it's easy to see Bailey's appreciation and relief.

This isn't the first time that Carmine has celebrated his local postal workers —the little boy dressed up as a mailman for Halloween and even got a tour of the post office because of his enthusiasm.
