So picture this:
You get a Facebook message from an old friend (more like a good acquaintance) who you haven't seen in close to ten years. It's a short message, briefly updating me on his life, saying that he ran into a mutual friend and they were wondering how I was.
You are pleased by the unexpected communication, tell him what you're up to, and ask the friend more questions about himself.
He replies, mostly telling you about his start-up company. And by the way, he adds, there's a company he's interested in investing in with a healthcare background. Might I be able to give him some feedback on the company and possibly covest/syndicate him?
What do you do?
a) Politely decline
b) Feel pissed off that he pretended to be interested in your life, but was actually using you
c) Ignore email entirely
d) Look at the company and possibly invest
e) Look up what "covest/syndicate" means
Right now, I'm going for a combination for b and c (and e). OK, admittedly, I have emailed or called someone out of the blue and pretended to be interested in reconnecting, when I was mostly in need of a favor. But that doesn't make it any less annoying.
