Oh ! My stranger in the crowd

I wave my arms frantically. I hope you would notice me, because well, everyone else in the crowded lunch room did. Eating my lunch alone was never my cup of tea, and I thought you knew it. But then, even when the entire room knew it was you I was trying to call, you were the only who acted as if you were oblivious of it. 

Maybe that should have been my first red flag
