That triangle that forms in the space bordered by your collar bone, neck and the upper part of the trapezius muscle when you lift your shoulders and push them forward at the same time?
It can hold rain water for your kittens or parrots.
It can collect only a limited number of kisses before it collapses and faints.
It can serve a sip of red wine to your lover.
It can warm up two fingertips before they slowly draw a path up the neck line or down the chest line.
It can offer the eyes a place to rest for a while and recover their strength.
It can host the title for a poem.
It can learn new things.
