Most likley to happen to me...

Time to pack, take finals, say goodbye, get emotionally ready, pack more, check for all my electronic plugs and cords, make sure I have all my legal documents, re-check for all my electronic cords, say goodbye again, re-re-check my packed suitcase, check for all my medications, say goodbye one more time, and then, FLY .... Then call home because I forgot to pack my toothbrush. :)
