For me, hug has a huge amount of "it depends". Its hard to explain, but here i go.
See, i can pass easily by a neurotypical person for those who not know me. I'm a very quiet/silent person, but under specific occasions (have to much to do, feeling overwhelmed by the noises and people, worries, etc.) i can be very agitated or shutdown.
When i get agitated i can talk too much, for my parametres of course. In this case i can hug someone, but has to be people i know VERY WELL and yet it feels akward and some times uncomfortable. I almost never initiate a hug.
When i'm in shutdown mode i get very weird. Even the touch can be like a
mental burn that provoke waves of anger and others feelings i can't seem to be able to named, all mixed together, even voices sometimes, if the person with me change they tone of voice. its had to deal with it without being rude.
Normally i dont like hugs too much or people who like to be very close to me (boyfriend never understood that, some times hug was too much and all i wanted at this time was push him away. In other times just a hug was the best sensation i could ever had, i know its controversial). I considere touch or hug without permission as very rude.
By nature i'm not the type of people who show affection,and feel very awkward when i do, so i would like people that i care about to know that through the efforts I make for them and the time I spent to keep them. I can not be the best company in the world or the best person to comfort someone, but I try my best hoping to be sufficient.
All this situations get me frustated sometimes, but it is what it is.
Aaahhh
, its hard to explain, there's many feelings and situations that one normally dont see around.
(sorry for the all the ramble)
