For me, it’s a hand at the small of my back. I can remember vividly who did that the first time for me when I was 14 and I was falling apart from fear. He came up behind me where no one could see and that hand… suddenly, I remembered to breathe. My legs (which were thisclose to buckling), got their strength back. He stood behind me, with his hand not moving until he felt I was ok enough not to collapse, then he walked back to his space without anyone knowing. But me. I can still feel his hand to this minute.
