It's totally fine if you aren't going to answer my letter. I realize it is an outdated way to communicate and that it actually takes time and a conscious effort, and that we weren't super-close friends to begin with.

But by God, do not get on Facebook to send me a message asking me a personal favor and then try to tempt me by saying that you are going to respond to the letter when you actually aren't. And please don't make a show of asking for my new address if you aren't going to use it.

Thanks.
