It’s funny. Your muscles have a certain memory about them. That’s why we can tie our shoes or play piano without looking. But then you spend a long enough time with someone and your bodies memorize each other you know? The warmth of your back, the pace of your heartbeat, your tickly eyelashes and the way your fingers would curl in sequence when I used to play with your palm. Another person is like moving to a new country where you don’t know the language. It’s a scary thing.
