I'm bragging to everyone that I'm a student at Stanford.
Why would you brag to everyone that you go to Stanford ?
Because it's a great school and I want to impress everyone.
I'm sure you're proud of being a student at Stanford, but it's wrong to brag about it to people. It makes you seem very arrogant and it won't help you make any friends. You should be more humble when you talk about yourself to others.
What's so wrong with bragging?
Bragging is a big turn off for majority of people. It is counterproductive if you want to do it to impress people. If you're really smart, people will see it through.
