Because doing so at the beach is considered rude .Because they had been told to always wear sunglasses at the beach .Because doing so can cause permanent eye damage .None of the above choices .
Why would they be worried about staring directly at the sun ?
I was the the beach yesterday ; somehow it was a rather quiet day at the beach ( for a Saturday ) . I was sitting on a beach towel enjoying the breeze and staring at the ocean , one of my favourite past times . At one point I took of my sunglasses and looked out . The sun was much too bright and I had to put them back on immediately .
