My mother always said she would come back as a seagull. A year after she died, I was driving down by the river and a gull came and flew right by my driver side window. Kept pace with me, until I opened the wondow and said
"What, Mom? You trying to die again? Go. This is dangerous!"
That bird flew away and no other ever came that close to me ever again. Coincidence? Probably! But it felt good to think Mom got her wish.
