As we have seen, the bottom line is that you won't give them up. For what they cost you, they have easily earned their keep and then some.
You are welcome to mine. I'm not going to go waste a day going to the post office, HOPING they have a small flat rate box, standing in line, telling the guy I do NOT want any additional coverage, stamps, delivery confirmation, or any of that other ****.
So if you are willing to come get them and save me from the time it takes to "give them up," come on down. But for what my time is worth, the time it takes to send them out is an upside down proposition.
In other words, I'm willing to give them up. I am NOT, however, willing to go out of my way to send them away.
Now, if you aren't willing to go out of your way and spend time out of your day to take them off of my hands, then they have obviously not earned their keep with you.
(on edit) the analogy of "proving a negative" comes to mind. Implying that folks who won't go out of their way to give then away somehow see value in them is the equivalent of asking folks to prove a negative.
