Ever since we graduated high school almost all of my friends have changed drastically. Now that they were studying, they suddenly knew it all and had opinions about anything and everything. In a cocky kind of way. It was so off putting I gradually stopped talking to most of them. There was just one person I thought really understood what I was talking about. He wasn't pretentious at all and we had much fun together. We started hanging out a lot up until this year. He decided he wanted to go studying too (he was working at the time) but was nervous and didn't feel like he was smart enough to make it. I supported him completely and was pretty excited for him, encouraged him to do the test. Finally he did and got in. In the back of my mind I was afraid that it might change things, but knowing him I told myself not to worry.... So a few weeks ago he started classes at the same Uni. And you wouldn't believe how little time it took for him to turn into this.... obnoxious tard. Now it is all about starting up a career, making money, looking down on people who are supposedly beneath him and pity them for no reason at all except that they must be terribly unhappy with their "plain" jobs and "plain" lives. People he used to work with, be friends with, just 2 months ago. The fun conversations are gone. It's all serious, all business, now. I feel disappointed, sad and especially pissed off. It seems that literally anyone can (and eventually will) change for the worse, even the most humble and laid back person. We do still talk when we see each other at school, but it's not the same. I don't bother anymore either. Have been down this road before with other friends and you can't make them see what you see. I know it's his life and he may do as he pleases, but it has left me pessimistic about people I meet. It's easier to feel nothing, have no expectations. Depressing.
