A couple of times I've brought strangers...

I'm the stranger who arrived earlier than you, and making introductions is the most reliable way of looking as if you've blended in.

It's also the good thing to do: nobody should be a stranger in a crowded room. Introduce them, get them talking to people, get them blending in, and more: get them *contributing*.

All this, and I say that I have 'no social skills': it's true when you look a little deeper.

Meanwhile, the small things we do may yet add up.
