The safest and most basic of openers
Let us not forget the all time classic of openers, the one that has graced our fabled society ever since the UK did us socialites a massive favour by banning smoking in pubs and clubs.
"Excuse me, have you got a lighter?"
For anyone wishing to erode their Approach Anxiety from scratch - especially if you're coming from a point of low confidence and a mistrust for unusual topics to the tune of "Hey guys, can I get a female opinion on whether or not magic tricks are actually tricks and not real magic?" urgh.
Believe it or not, these ridiculous openers actually break the ice if you've got confidence, timing, and a smile on your face. But if you haven't got all that, and you happen to enjoy smoking - asking for a light could be your first baby step towards realizing that most strangers enjoy being chatted to and do not have the sharp teeth you may think they have.
I usually go off on one like "Excellent! Thanks for the light, this random girl stole my lighter without realising - don't you just hate it when people do that?" (...teasingly putting their lighter into my pocket and continuing to rant)
For all of you smokers out there, here's a silly piece of advice to try out. When you go out... Never Carry A Lighter
Before I knew about PUAs etc., (and thereby actually learned some tried and tested conversation-starters), I think I probably wouldn't have met one of my previous girlfriends if I'd been carrying a lighter that day.
