It is a working visit to discuss some specific issues and exchange ideas. Perhaps, Queen Rania had other engagements.
On a different note, it is nice to know that Belgium has got the Prime Minister and government now. Hopefully we shall see some state visits.
"To watch the sun sink behind a flower clad hill.
To wander on in a huge forest without thought of return. To stand upon the shore and gaze after a boat that disappears behind distant islands. To contemplate the flight of wild geese seen and lost among the clouds.
And, subtle shadows of bamboo on bamboo." Zeami Motokiyo
