Friends by Calendar?
… if she is a friend, any day is the right day, any time is the right time, and any moment is the right moment to give me a call. Send me a text. Hug me. Inspire me. Love me. Think about me. Accompany me. Wish me well. Stand by me. Walk with me. Laugh with me. Play with me. Talk to me. Hear me. Surf the seas. Swim in the lake. Have coffee with me.
Between friends, there are no markings on the calendar.
