Why is it soo hard not to care or give a damn about people? Maybe if you are promoted to GS Mods you will get to learn that very skill.
For them its like:
Rule#1: Follow the GS Policies and do not treat others unfairly. Only if they violate these rules are to be warned, temp banned, or perma banned.
Rule#2: Ignore rule#1 and go nuts on ppl you dont like or feel annoyed from.
But in college life. The only way you can make others jealous is that you live your life and be yourself. And dont care about this girl whom you are jealous with. If she is a friend of yours. Be friends with her, smile, have fun, chitchat and study to do well in the univ.
Forget about the girl. Either curse her, or wish her blessings. Either way you need to get over it, and move on so you can do better.
