In school I was embarrassed about the clothes I wore... also the calculator I had and my shoes and my lunch and my trapper keeper and my pencils...

Kids being embarrassed at school is unavoidable, being embarrassed is practically the job description of a teenager and younger students often have their own insecurities. There's an interesting debate as to whether these embarrassments are good or bad for us in the long run but we can side step all of that... not having access to a smartphone is important - it's important enough to warrant the slight amount of embarrassment.
