Time travel - it’s real.
Let me clarify that, though - the time is always one you have lived; the travel is always transportation of the mind.
The quickest way to transport someone from here to there is with a simple question.

Tell me about your family growing up?

I watched an octogenarian’s eyes twinkle with joy and longing as she talked about her dad.
Oh, my daddy was a wonderful man. He was a sweetheart. He would take me and my friends to the movies and just sit in the back row. He was wonderful.
She was no longer a woman riddled with loss -
loss of health
loss of loved ones
loss of independence
loss of naivete

She was full of love and hope and memory.
Sometimes the memory of what was sustains us in the reality of what is…as she returned from nostalgia, it was bittersweet. No longer is she the center of her daddy’s world. No longer does she even have a daddy here on earth to call or write or go and visit.

But to travel back, to be present in the past…it is a holy gift, an echo of eternity’s stamp upon us.
