I don't like when people say, "you tend to dislike in others the same thing you dislike in yourself" because I don't think that's very accurate.
I dislike when people are chronically late. I am always on time.
I dislike people who do drugs. I have never tried them.
I dislike hypocrites. I am not one.
I dislike a know-it-all. I will come right out and say, "I don't know much about this, but I think..."
But then my Aunt, who I always thought was very wise, often says: "Everybody Is Everything"
Your girlfriend is being bitchy? Your best friend is moody? Your mother is a mensch? Your co-worker is a brown-noser? Your boyfriend is acting weird? Your classmate is getting on your nerves? Your husband is being an asshole? Your sister-in-law is saccharine sweet? Your mother-in-law doesn't like you?
At one time or another, as much as you think you are not any of the things you see in others, it is most likely inevitable that you are. Sometimes. Even if only once. However brief, it's probably there.
Everybody is everything.
(Really though, I'm never late.)
