You take an aisle seat because it suits you to be able to get up and down. some people take a window seat because it suits them to look out the window. You want to look out the window that badly take a window seat.
Hmmm..... there seems to be communal blind spot about this that is worrying. The window is not for the sole and exclusive use of the person sitting closest to it, just like the aisle is not for the sole and exclusive use of the person sitting next to it. Both are shared assets. Nobody owns them. You don't even own your seat if the cabin crew decide they need to use it for another pax. A plane is just another form of public transport, as I've heard being mentioned before.
You may choose a window seat because you don't like to let other people past you, or because you like to sleep, or you want the best view out the window. BUT THE WINDOW DOESN'T BELONG TO YOU AND BLOCKING THE VIEW OF OTHER PASSENGERS IS ARROGANT AND RUDE.
On the rare occasions when I find myself in a window seat I am very conscious of my travelling companions desire to check out the view, particularly during takeoffs and landings. I will continue to do so rather than be a prat.
Seriously , listen to yourself.
