for me: 1 day, for you?
365 days, enough? too much or too less?
N years ago, a friend of mine: when he left family back to H.K. he always cried for several days: wife, son, daughter live in another side of the ocean, he himself was along in H.K. as a Sr. VP of a big org.
N years later, when the kids finished university, 4 of them, sent me a family pic. wow, how many days of Distance Love, can you count?
Love days: countable? you better stay with your mom and never leave your father along, else, you might forget your last name or, whose son you are!
that's period.
