Groups
On entering a networking event, choose to join a loose group of two or three, especially if one of the three is looking around and isn’t fully engaged.
Don’t push into a tight-knit group who are animatedly talking and leaning into each other, unless you know one of them well; this is a tough crowd to start with.
Also be aware that the person standing solo might be standing solo for a reason – but that doesn’t mean don’t talk to them. If you’re new and don’t know many people, even the boring person might be better than standing alone yourself.
