People I don't know

I didn't catch their name.
They sounded Russian, but I am not sure.
They were actually a bit of fun.
They were just posing for pictures.
One would take a snap, then the other.
I offered to take one of them both.
Right after I handed the camera back I took this.
It is a metaphor on perspective.
Neither of them could take the picture.
They needed someone on the outside to do it.
So it was just a chance meeting in Boston.
I am sure I will never see them again.
They probably will not remember me.
Even when they look at the picture they have.
But our paths did cross for a small time.
And I hope they like the picture I took for them.
