Well, as said before I never close the shade :
1) When sleeping my eyes are closed, I don't mind any light, you could just put me under a neon lamp and I would be peacefully sleeping
2) At night : yes, it is dark outside, but I love to see the reflections of the strobe on the wings, see some cities passing by underneath or some cloud formations which you still cn see when it is not pitch black.
3) I get claustrophobic (sp?) if I am sitting in such a small room like an aircraft cabin and have only the wall/closed shade at the one side, the head of the neighbour or his newspaper at the other side and the seatback of the front row in front of me.... I need a free view to breathe!
4) I doubt that when I am sitting at the window my seat neighbour will be disturbed by the light coming in. When I sit at the aisle or in the middle seat, I usually can't even see the window as such, not to speak from some "disturbing light".Best regards,
Well, I am flying a lot, both private and business and still enjoy every single sector - except when there is no wioutside view....
