"On Your Left" will never sound the same to me after watching the movie "Spanglish". One of the main characters is a thirty-something married woman who spends her days jogging around her ritzy neighborhood and her nights chasing another woman's husband.
As she jogs through the neighborhood, she can not stop howling over and over "On your left...on your left". Usually, the only people walking on her street are other housewives, strolling slowly with a friend, or the maids and yardmen, slowly trudging from the bus stop to their jobs. But, one day, she is behind some male runners who respond to her "On your left" by speeding up and trying to outrun her. She chases them down, one by one, still howling "On your left" as she goes by.
After she has offended her own housekeeper in countless ways, the housekeeper is slowly walking from the bus stop when "Mrs. On-Your-Left" come running up from behind. Wanting to somehow prove she could hold her own with Mrs. OYL, the housekeeper takes off running, wearing a long dress and dress shoes...when Mrs. OYL finally passes her, Mrs. OYL makes a gloating remark...the whole OYL deal is just her way of rubbing people's noses in the dirt.
