'This Is Us' is done forever. The cast had some lovely mushy things to tweet.

That was us.

NBC's This Is Us, the six-season drama that became notorious for making us cry, aired its final episode on Tuesday, closing the book on the Pearson family forever.

It is the end of a wonderful era. We yelled NOPE multiple times at our screens, and cried out "brutal goodbyes", as well as saying brutal goodbyes.

The cast, crew, and fans of the show took to the internet to express their feelings for the final episode of the show.

The end of This Is Us has been a lovely march for those of us who have worked on it.

It is not lost on me that there are so many shows out there. I just want to say thank you if you spent any of those hours with us.
