You can deem it as arrogent if you want, but I call it blunt, honest, and true. Too often on SDN people say things to others to make others feel better (or make themselves feel better). It is often seen by people saying things like "your undergrad school doesn't matter in terms of getting into med school", "GPA and MCAT aren't everything, you have a shot at Harvard with your 3.3 gpa 32 MCAT", "where you go to med school won't affect your residency". This can make people feel better but I prefer people just give me the honest truth of what they know, and I know many people at UCSD med school and none of them chose it over UCLA. UCSD is an excellent school in an excellent location, and anyone who goes there should be proud, but don't pretend that it is your top choice while you are on UCLA's waitlist when you know you'd go to UCLA if you got in.I like how this doesnt strike you as an arrogant comment.
Basically, I just want people to be honest with their top choices, even if they don't get into them. If you end up at a school that wasn't your #1, it is ok to acknowledge it.
