'Whose sitting in my seat?'

Will is very kind.He knows I love the window seat when flying.When we got our boarding passes today I saw that my seat was 20E.20E is not a window seat. 20A or 20F are window seats.Going down to Melbourne Will was in seat 40F and I was given 40E but he let me sit in 40F.....'that's kind!'They'd given Will the window seat again!"Do you want your window seat?" I asked him today as we approached the steps of our flight to Brisbane."Yes, it might be nice, I could look out for awhile and then read my book," he said.I made sure I beat him to the steps and was up first.....the window seat was mine!.....Muaahahahahahahahaha!We made our way up the aisle to row 20 and there sat in the window seat, 20F, was an Asian girl.I was miffed.I know these window seats are popular but I was thinking 'don't you think just because you got to the row early you can squeeze into that seat, dear!'"Excuse me," I said, " I think you are sitting in our seat."She looked bemused and looked up at the row number."It's 20 F" I said clearly."Yes," she said, "It's the seat I have."I was clutching the ticket for seat 20E so it was no use showing her that...."Will, your ticket," I ordered as I looked at her sternly."Oh, mine says 40D," said Will.I forced a sudden smile and sank into 40E......"I'm very sorry," I said, turning to her and wishing desperately I was somewhere else."It's fine,' she said magnanimously.Will read his book, 'She' looked out of the window for five minutes before closing the blind and falling asleep. I spent an hour and 50 minutes staring at the back of 19E.2015 has been a big disappointment to me so far!
