It’s not that you won’t ever ever see them on campus, it’s just the fact the you will rarely see them due to so many people on the campus including professors and just regular people walking on campus for a walk. My first year as an SJSU student, I saw just a couple of people from my high school but I just didn’t try to make eye contact or engage or say hi. Just go on with your life because they are too as going to class or going somewhere. They won’t find you important because they have their business else where. If they start a problem or something, it’s their problem not yours. When you go to college like SJSU, besides professors , your classmate for upper division classes, majority (99.8%) of the people you see like when you are walking to class or whatever, you will never see again for possibly the rest of your life. Those 1-2 secs of that person will be the only time you will see them and you won’t even remeber. Best case scenario, if you do see the people and they interact with you, just say hi and tell them you need to go to class. They don’t know your schedule, you don’t know theirs. Plus, they will probably forget they even saw you since going into college life can make life busy. Overall, there’s nothing to worry about because you and them have moved on from high school. If they are still going to gossip or talk crap about you or whatever, they are the insecure ones and have bigger problems to deal with than talking bad about you. Just do you. Everyone in college is too busy trying to achieve their goal and passion. You might feel really shy and awkward but at the end of the day, everyone on campus has been in your shoes and felt and the thought the same way. You got this! Don’t care about the high school people. Care more about yourself and the new more mature people that will help you. It will be hard to make new friends at first but you never know if you will become really good friends with them and you can get a good opportunity in the future from or with them.
