P&S, if unexpectedly you were to run into your country's leader. what would you say to him/her. ?

I would quickly look for the nearest fruit stand to grab something to throw. 

I'd say "Thank you for ensuring that your gov't has done the right things to minimise the effects of this pandemic.  The idiot in the U.S. has really made a mess of it."    

The usual courtesies, like wishing him luck in the upcoming election.

I would say. Boris me old fruit, now that you got us out of Europian Union. NOW, WHAT? do you have any other bright ideas? 

shake their hand i guess , ....

I'd say 'All right Boris!' That's it. 

I would tell the loser Trump to resign immediately. That is the only way he can Make America Great Again.

🥴 Nothing. 

He'd be surrounded by ppl with COVID19.

"THANKS MR TRUMP FOR BEING A GREAT PRESIDENT"...I WOULD ASK HIM TOO IF I CAN HUG HIM...IF SO I WILL..

I would walk right past Trump
