If you spend your time in a corner with close friends, that may be fun, and safe, and all that, and yeah you'll be seen at the event, but it likely won't do anywhere as much good for your business as getting outside your social circle and meeting other people. In fact, if you seem to want to stick only to your friends, it can work against you.
So don't really ignore your friend at networking events. Say hi, maybe spend a few minutes, but then move on to see who else you can meet.
A twist on this that can work very much in your favor is to ask who ever your very best friends are in the room this question, "Who do you know here who would be the very best for me to meet for my business, and will you introduce me?" Then when they introduce you as their best friend or at least a really good friend, if they have good relationship with the other person, you'll get some of their borrowed trust, which is a great benefit.
It's great to have lots of friends, but they very likely won't be your only customers or clients, so spend most of your time with other people at networking events.
This post is one in a series on how to make the most of in-person networking events. If you're going to go (and I suggest you do if your business benefits from relationships), you might as have the most fun possible and give and receive the greatest benefits from the occasion.
