I'm thinking it works like this.
We make our selections differently when we know that we are going to show them to the world.
Bit like picking your nose.In private I might or might not do it all the time.But in public,never.
Every year,about this time,I learn things ready for next year.But every year these things I learn don't help.
Think I might have to write a book and have it superglued to my forehead.Better still,chop off my head and superglue book onto my neck.
