I keep thinking about this post.
Honestly, while its a bit brusk, I don't think its rude. It actually lays out what people are told all the time in this forum - it explains the person's feelings, what she'll do, and what she can't do.
In this case, for whatever reason, the person who sent this email is being put upon. She probalby feels that whatever hints she's been throwing have been ignored (or not picked up on) and felt like she needed to lay it out on the table. Really, what she said was:
1. She didn't have any work currently.
2. Lots of people are interested in these jobs, and everyone has relatives and friends asking for them.
3. If she hears of anything, she'll tell you.
As a person who often gets asked for "favors", its pretty easy to get burned out and start feeling like you are only needed for what you can do for people. Especially when you don't have anything you can do for them, and they keep asking. Now, I'm sure you didn't mean for her to feel like that. I personally would apologize, and then wait for her to come forward with work. Your boyfriend should have his own contacts as well by now in the organization.
