Whenever I'd vent to my father (who passed away in 2005) about "other people" he'd say "Who would you compare yourself to?", which gives credence totally to the concept of yinyang, I feel. Everybody vents, everybody has someone who annoys them at some point in their lives. It could be someone close to you, or it could be a fellow co-worker, a neighbour?
But, the point is, it's human nature to vent. At times, though, you have to know when to stop and when I get to that pinnacle, I think of my father saying this to me...because it's so true, but in a funny twisted way right? You actually do need that polar opposite to understand yourself and your own faults!
Next time you find yourself at that frustrated level with anybody, think of the "why?" before you continue on your rant. We need this bit of conflict in our lives to teach us how to be better people. And, when someone isn't conforming to the way you think, you may be the object of their rant. It's highly possible that if you are having issues and feel the "seemingly contrary forces", they are as well. So, although, you are polar opposites, with that person, at this moment...there's a reason for both of you being in the same circle and you must think sometimes "How does this person enrich my life?" A different perspective is always a good thing.
Follow the "Who would you compare yourself to?" advice and get over it!
