Little Kid Ghost?

I am going to tell you guys another true story that happened to me in Maryland in 2011. My wife and I rented a house in Waldorf MD, I never felt right in that house. When I looked at it from the outside, it looked a little dark, even during the early afternoon. The house had wooden floors throughout the living room and kitchen. When ever I would watch TV by myself downstairs I always heard little foot steps behind me. When I turned around to see who/what it is, they stop. When I would be by myself in the house upstairs, I always felt someone watching me. When I got halfway down the stairs the feeling would stop.

My teenage daughter would tell me all the time " Daddy I think we have a ghost/presence here in the house." My wife didn't believe us.

One day I was upset with the ghost and I heard footsteps go to the edge of the living room, so I went to where I heard the steps and I said " Show yourself, I know you are there." The footsteps then went away from me and walked over to the other side of the living room. Again I said " Show yourself". Nothing happened, nothing appeared.

We lived in this house for 2 years and I never saw anything but I for sure heard things and felt things. I was always on guard at the house. I never could relax either. I read on the internet that a 5 year old girl got shot to death by a stray bullet at our house years earlier (like 1999 I think). We had a little playground thing in our back yard too. I think maybe she is the ghost at our house? Please tell me what you guys think. No jokes or smart remarks please.
