Often we overlook the thin line between judging someone and disliking someone. Could it be that we judge, hence we dislike?
At which point do we decide to pass that daunting judgment; to simply sum one up and "dislike" someone? Has it occurred to you that you are in no position to sum anybody up, let alone decide that someone is worth disliking? Yes, you have.
Then stop it.
The only reason why you are disliking anybody at all right now is thanks to that smug voice inside of you going "I've got this person all figured out and...naaahh"
Hypocrite.
