There are more dead people in our world than alive. So here's my question - WHERE ARE ALL THE OTHER GHOSTS!??? If he can spot ONE neighbor, how come he can't see more?? Life after death, seriously, must it be so awful !? I'm sure OTHER ghosts have it hard and feel lost too. I can only imagine it like being in a A.A. meeting (but with no coffee). If I were one of these ghost, I'd ask all other ghost to get together, and we make efforts to make ourselves known to the living world (or do something more eventful), anything but mope around stalking your spouse, watching random people doing mundane things. How dreadful! Life in prison sounds more attractive.
Ok I get it. He can’t go “ANYWHERE”. He’s “STUCK” in the same place no matter what. It just repetitive. Basically, “Cycle of Life” . When you hear cling/clanks at night, don’t worry. That’s just YOU making noises in the after-life.
As for the pie eating scene : I KNEW she was gonna throw-it-all-up! No skinny girl’s gonna allow all those calories go to her waist.
