The walk

We took a walk along the beach together, a slight chilly breeze, besides the crashing waves leaving our footprints behind us. Our laughter echoed in each other's voice. I playfully threw water at you, from my bottle, and made you wet and cold.
And that's the mistake for which I'll suffer... for long...
I turned back to look... and didn't see you, only indelible footprints in the sands of time.
Did you not even once think? How could you not hear the painful silent words?
But no, you just left me those footprints, to figure out how to erase them.
