Does anybody know how many people we only meet once throughout the course of our lives ?

Question

I was recently out and about and had a number of really interesting conversations between 'a' and 'b', which enduced the thought which prompted me to ask this weird question.

I know, strange things for strange folks.

Answer 1

God alone knows. But who is counting?

Answer 2

Well for me  its been about 3 times so far. This one lady spoke to me in Hyde Park, London and was asking me for directions and we had just a little chat about travelling around.

Then there was someone who complimented me during travels too and another tall person I bumped right into (I hit his chest with my face haha).

Answer 3

Thanks for the 2 points.

Answer 4

Everyone you have ever met, you met at least, once.  So it depends on how much you get around.
