I was sitting here on the computer on yahoo answers last night and I felt something touch the back of my neck so I moved my shirt up so it would go away but it took a few seconds to get that feeling off.

I have come to the conclusion no one has died in this house. i looked up the peoples last anems on my mailbox and nothin came up.

Maybe it is someone from the land but I don't think anything happened here that I can find on the computer.

Or maybe its someone I know?
Which is either my grandpa or uncle or could be my mom's mom or dad but I never knew them.
