I keep re-reading my submission even though I've already sent it.

Someone mentioned a summary and I was like, "Crap, did I include a summary? I don't remember doing that." (i had done it). Did I include all of the header? (i did) Did I remember to include the story itself? (I did)

Re-reading it several times, I've already spooted several points of "um... what was that supposed tos say?"
