"Hi, not lunching?" I asked Elena when I noticed she was alone at her desk.

"Yes. Later."

"Busy?"

"Yes."

"Oh well..." and I walked off, with somewhat a heavy heart as she seemed to be very indifferent, answering my questions merely out of courtesy.

I shouldn't and don't want to give up. She might be really busy; nevertheless, my mood hit rock-bottom today... :(
