So...I had a wee bash at another spirit drawing. I am still kinda in the fence with this whole spirit drawing thing and posting to Facebook. How do u make it less generic so that it can only be specific to one person out of thousands?
I try and be strict and make sure that the person trying to claim the drawing can take ALL of the information. But I have found that claiming all of the information is sometimes not viable...let's face it, I don't know everything about my deseased loved ones. So I find myself gauging what info they can take...is it the more generic stuff or the more specific stuff....it's hard to work out. So...anyhoo....here is another one...
