When two souls fall in love, there is nothing else but the yearning to be close to the other. The presence that is felt through, a hand held, a voice heard or a smile seen.
Souls do not have calendars or clocks, nor do they understand the notion of time and distance. They only know it feels right to be with one another.
This is the reason why you miss someone so much, when they are not there - even if they are only in the very next room. Your soul only feels their absence - it doesn't realize the separation is temporary.
