Barack Obama offered a brief reminder Monday that presidents can speak intelligible, complete sentences on subjects they’re qualified to speak about.

The former president didn’t take any overt shots at his successor during a lecture at the University of Chicago, where he once taught constitutional law, but his talk stood in stark contrast to this weekend’s bewildering Associated Press interview with President Donald Trump.

The differences weren’t lost on social media users.

Hearing President Obama speak reminds me how much I miss having a president.

It's so strange watching and listening to President Obama right now. It feels like ages ago that this sense of calm I feel was mundane.

Listening to President Obama speak delivers an unbelievable sense of calm & motivation. I miss having a President who I love & respect.

Daily reminder that it's been 51 days since Trump accused Obama of a felony and still hasn't provided proof or apologized.

@ABC @SagArcher Listen!!! Intelligible words! Noun verb agreements, and not one "disaster" "tremendous" to be found. Thank you, @POTUS44
