not necessarily a theory, but moreso an opinion.
Ive been dealing with a whole lot of mixed emotion garbage here lately, and its starting to become really clear how close one emotion is to another.
My ap english teacher (who was 100x better than both of my professors) said during one lecture that "love is the closest neighbor to hate." I know this is true b/c I have extreme feelings of hatred and anger towards my ex for the way she treated me at times, and then other times I just want things to be straight between us so I dont feel that way anymore. The more I thought into this quote, I really think you could change those two emotions out with many other forms. Such as "ignorance is the closes neighbor to the truth."
I don't know, post your opinions b/c I think you can have pretty good conversations about the truths or untruths behind it.
Lately Im dealing a lot with the hate, love, pissed, seclusion, bliss...too many at once i must say(for me)
