for the first time, I read something using the 2 words "nodded abstractly". I Google it. People use it quiet often...
I read it there:
“Welcome aboard,” said Justin, one of the programmers. He stood up and grabbed a rubber chicken from a nearby desk. “Kevin and I are going to integrate our changes now,” he announced to the rest of the group. A few people nodded abstractly, already intent on their work.
My question is, how can a person nod abstractly or in an abstract way...?
