Let me try to explain, 
this is not what I mean:
 

The feeling from your favorite blanket during thunderstorms -
when the lighting flashes, the power is out, and all there is are candles and the sound of rain.
The warmth of the sun on your skin -
sitting in the grass with coffee and biscuits because it’s finally spring.
 

Comfort like... 
a quiet locking of eyes, with that special person, -
and you don’t have to say anything because you both know.
Shocked giggles with your friend -
because you both do that thing with your lips when you’re nervous, and you just noticed.
 

Stuff like that.
The irreplaceable and inexplicable feeling of someone being there -
for anything, anytime, anywhere.
Someone sees you, hears you, feels you -
every part, every time, every inch.
 

Comfort in a person.
That's what I mean.
