I’m not an expert.
I’ve just made it to middle age with a support network made of people from all ages and walks of life.
But I’ve learnt over the years how to do this. I was not born such a social butterfly.
If you’re working on establishing a rapport with someone, start with good eye contact. And then compliment them. Nothing creepy, just a comment on how they have a nice smile or how you like their boots.
And if nervous, tell them. Be upfront. Be honest. People love and tend to respond well to a little honest vulnerability and imperfection.
Then strike up conversation. Mention why you’re in the building or waiting in the queue, if appropriate.
If all else fails, talk about the weather.
And if you see them again, say hi.
You may have just made a friend.
