And then a few more later.
By the time we sat down to open some of the presents almost all of them had a tear somewhere in the package. My cousins (who were scared about it) told me it was their ghost and every since then I believed them.
Who else would tear all the presents open? Seemed weird to me ...
skeptika's note:
This is a cute and original little story. For that reason it gets posted even if it is not about a paranormal experience. I would be interested to hear other stories where something that was reasonably concluded to be a paranormal experience was later proved to be mundane. (Note the use of the word "reasonably"!)
