I've always been repelled by these two:
The ones who do not talk. I feel I should fill the gap, that emptiness so I talk. And at some point I feel tired and also insecure and I give up.
The second ones are those who do talk and are not afraid of using any words with any tones. Usually they have no tolerance if you learn the way they talk, they're not pleased with tasting their own medicine.
Considering the fact that they are in minority, feeling healed must be doable after all.
