Well shit-on-a-stick...who knew?
Turns out, while Josh, Suzy, et al. were summoned to the kingdom of heaven you were LEFT BEHIND. You're uncertain, but confident it has something to do with a little incident with your Mom walking unannounced into your bedroom late at night when you were 14 years old. Regardless, the damage was done, and now you were earth-bound while everyone else got to experience the joys of heaven.
You feel...so alone. Probably because everyone else in in heaven now.
