Damsel Rescue in the works!

walking down the road...only to notice a huge caterpillar hanging on a thread (could be a spider-web), hovering close over a passerby's head (a lady).....only to have it yanked and chucked away by a man in a dirty banian/lungi walking behind her....with a big grin on his face! Makes me wonder what the "emotion" was for....(was it because he performed a heroic act of rescuing a "damsel" in distress?)  Let the laughter roll in, please...
