July 20 will go down as a dark day in our country’s history. But particularly in the midst of trying times, it’s important to remember the qualities that make America exceptional.

Twitterers came together to commemorate the momentous event:

While we are capable of taking ourselves down, we also have the ability to better ourselves and triumph over adversity.
