IMHO - There are 3 distinct types of conversations at professional events.<p>1 - I want to sell you something. (Something can be part of a company too)<p>2 - I want a job.<p>3 - Let's connect and be friends. (This includes "Let's hook up" but that's a dangerous objective at professional events. And would require much more space)<p>If you go too quickly down one path, and then switch to another, it looks insincere. This is also why it's hard to sell to friends. If you're pitching a VC, and then ask about their kids, it's awkward. If you're looking at someone's dog pictures, and then ask them for money, you look like you were faking the interest.
