Supreme reverie when you get a letter sent by the loved one. When you are reading it, the scenery changes completely and you find yourself instantly transported in a world of love by the mere force of the other's mind. You then drink this letter as if it were a refreshing nectar.
You follow the rhythm of your heart and the rhythm of the words, and these words become the notes of a Hymn to Love. The emotion gets stronger, the adrenaline rises up, like in the moment just before making love.
You read on and you remember some high moments of your life, and you thus remember that life is worth being lived.
You read it again and again and again and it gives you strength in moments of doubt.
You will eventually vanish, but the letter will remain as the witness of your emotion.
I hope the sensual emotion brought by a letter will remain he same when love is brought by electronic mail; though I strongly doubt it.
