The serenity to accept those things which I cannot change

Delta is failing to get me home tonight. Maybe this is partly just the chances from leaving from a small airport at 6pm. The scheduled plane out was delayed, such that I would miss my next plane. There wasn't a later plane from there. There wasn't a route through somewhere else I could get on. Now I have a surprise night with my parents, or half a night anyway until I get up at 4:30am to try again on the first flight out tomorrow.
