Why are teens so embarrassed?

Hello, I love your books! There very realistic and it’s almost like you read every teenager’s mind, even boys. I remember being a teenager and reading The Alice Series and agreeing that almost everything that happened to her was embarrassing and some of those things happened to me. I wanted to ask you, why do you think teens are so awkward and embarrassed all the time while adults are more calm about certain things and don’t often get embarrassed?

I still remember awkward and embarrassing things that happened to me, and I always think that whoever saw it happen is right now, this very minute, remembering it too, even though it happened 50 years or so ago!  I especially remember the first time I realized my eyes were very sensitive to the sun, and I had no sun glasses.  I was 16, and ready to cross a busy street, and my eyes  began to water.  I had the feeling that every driver who passed me saw the tears on my cheeks and thought I was crying, and I was so humiliated.  The older we grow, the more we laugh at things like this.  Gives us something to talk about at the dinner table!
