Groups of 4+ are the big challenge for most people; whether it’s the approaching, the entering or the leaving. Let me say here and now, until you’ve got your ‘L’ plates off, don’t start approaching groups, particularly when you don’t know anyone. Needless to say, it’s not so bad when there is at least one member of the group whom you know, but, even then, it can be a bit daunting.
The group to approach is the one you feel most comfortable with. Firstly, I’d like to suggest that you aim for groups of three; groups of four or more, even for me, are a big challenge. Sticking with this group of three, decide whether you are more comfortable with males, females or a mix. At the same time, decide whether you feel at ease with small, medium or tall people.
Personally, at 5’ 6”, I would never approach three dark-suited men who are 6’ tall; talk about being out of my comfort zone!
