Manners?

I view it as they just don't think you are a good Match.

No problem, I understand. I hope your EHarmony search goes well, and you find what you are looking for. I would hope they feel the same for me.
Thus, "Good luck with your search".

I suppose if you live your life with the view of the glass half empty, it is always rejection at its core.

I suppose you don't see any use in saying Please and Thank You anymore either?

Whats the point, right?
Especially Thank You. Its "after the fact", so it doesn't gain you anything, right?

Yet, I say Thank You all the time.
Why?
Because I like to treat people how I would be liked to be treated.
