acknowledge me!!!

i get mercilessly teased at work for repeatedly calling out assistants' names until they respond to me and ask me what i need.
Is this essential behaviour for me to function at work? or is it a self obssessed need to direct others acknowledgment of the things i say and do?

Above is a still from Guerin's TREN DE SOMBRES, a film that i think has a lot to say about acknowledgement.  Featuring lies and truth and a real place and a fake history, the intersections of knowledge and memory are confused. But people, be them real or fake, exist in this unique film universe.  And people in TREN DE SOMBRES are often posing for photographs, or in idealized actions like family picnics or bike rides. Or they are engaged in work that is the foregrounded activity of the frame ( a man raking leaves.)  They are sometimes/always  ghosts, yet their visibility is never doubted because they are looking back as we watch them. As you can see from the picture, these people have a modern need for acknowledgment.
