what is this type of body language?
SweeteDee: a man, straighten up in his seat after lounging his arm of the right side on the chair beside him and turning his body to the side where is female friend was sitting in another row and he could sort of see her sideways. but when a very younger female whom they know and he knows for a while, came in the room, he eventually noticed she was there sitting behind him, he suddenly straighten up and turned forward in his chair. then few times he turned his head to his left side where he could see her instead of the former female who was sitting behind in another row. he ignores and acts indifferent towards the younger female. (sorry if its confusing)
