This week, Donald Trump travelled to Brussels for a meeting of the Nato leaders. It's being closely watched as part of his first foreign trip as President.
As is tradition from when the leaders of the Nato countries meet, they posed for a photo. And er, Trump appeared to shove the Prime Minster of Montenegro out the way to get to the front of the pack.
For comparison, here's a picture of Trump at the photo line.
And here's a picture of Barack Obama posing with the other NATO leaders in 2012.
In fact, Obama seemed to be having a lot of fun at the NATO summit in Chicago.
He had a laugh with the Secretary General.
Remember this guy? They had a laugh too
Manners maketh man.
