Last time I took a long flight I woke up from a nap and was very disoriented and next thing I know a lady was saying 'Oh no! Are you okay!' and there was a flurry of attention and I was lying on the floor and my head and knee really hurt and I was given smelling salts and an oxygen mask was placed on my mouth and had my head was laid on a handsome flight attendant's lap in the middle of the aisle and the nice Captain of the airplane came to check on me.
So I'm just a little nervous about this long-ish flight. Sure, it'll be fine. And then of course the plane will land and it will be grand. Talk to ya.
