Am I being unreasonable feeling a little miffed by the guy in front of me asking if he could close one of my three blinds?
The flight left at 18.20 hrs, it was a 777, six seats if F, and I was enjoying the bright and open seat space. However, immediately the seat belt sign was off the guy closed his blinds before he asked me.

My instant reply was "of course, feel free", and indeed he did.
Then I felt that "my space" was darker and not just as nice. In reality, I wish I had said to leave it as it was for the moment, especially with it being so early in the evening. I would not have been bothered had it been later on by a couple of hours. As it was I'd have felt selfish to say no when I did after all have three windows. But then so did he (that's my reverse logic) and I did not ask him to keep one of his open for my benefit
I have not had this happen to me before and I don't know if I would be so obliging the next time. I just don't like being put on the spot, I guess.
