I don't know about you, but no matter what email, wink or hello comes my way, I always reciprocate with a response, even though it may not be a response the other party may be hoping for . However, I feel it's always a respectful thing to do when a person is making an attempt in his or her own way that they are interested.
I just think it's a kind and respectful gesture that one owes another because the person decided to be on an on line website. It just makes clear blue sense to be respectful to the other party no matter wether you are interested in him or her or not? Just asking if others out their feel the same way?
Happy New Year,
