if you could complain about just one thing

If I could complain about one thing...I would complain about other people minding their business. A lot of times, people are too concerned with other peoples lives...especially when they have a lot going on in their own. You can't say what you "would have done" if you were in someone else's situation. You should just be worried about what you're "gonna do" in your situation. If I had one more complaint....I would complain that others are too worried about someone else.
