KSinghni,
I agree with your concerns, but girl, you spend way too much time looking around at other people, searching for faults and then dwelling upon them for such a long period of time.
There's a fine line between realizing that people are wrong and between judging them to a point where you're essentially looking down upon them.
I was once told by a Gursikh, that if you laugh, take happiness or even put down another Gursikh for no particular reason when they committ a mistake, that mistake will probably be committed by yourself, sometime down the road. I don't think you went THAT far, but you were still feeling quite negatively about what you saw.
If you saw people socializing... do what Vicky Singh said. Either talk to them about it in a kind, caring way or stop thinking about it! It'll eat away at your soul - all of the negativity, judgementalness, etc.
Most Gursikhs simply look at people like that and try to think the best. Don't get so down!
Cheer up! Guru Nanak's Sikhi will never be empty of true Gursikhs... and there are many out there - so don't despair.
Gurleen K.
