Coincidence - Small World Edition

Life's little coincidences continue to amaze me.  This week's example...

I know a total of two gents who drive trains for a living (one is LJ's own cuboz). 

Both are gay.  And if I may say so, both are charming handsome men.

I met them independently of one another.  Meetings were years apart.

Both live in Sydney, Australia.

I learned that they, in fact, know one another.

The statistical probability of this coincidental association is vanishingly tiny.  I say it again... amazing.

Or maybe I just like trains...
