I found this on wearestorm twitter page. This makes sense to me how they are signaling to each other.
1) WATCH THE WATER is addressed to {them}.
It is how we are publicly signaling deals to {them}
North Korea calm water picture = deal accepted.
Trump Pence water off the table = deal rejected.
Cont...
2) Netanyahu to Iran water on table = deal offer.
G7 leadership calm water photo = deal accepted.
Manafort “plants need water” = deal offer.
Without water, everything dies.
Add: Fiji water bottle (2 hands) + water glass (2 hands) = Consuming THEM / Arresting THEM
Good stuff re: water!
PS I still think Trump and Pence removing water and napkin was for a photo with Melania .It was her first day out.Water bottles in front of the First Lady would not have worked.And yes they did take pictures from that meeting.
