Small Jewish World?

Last week, three hours into a four-hour wait in pre-op, I posted this status update on Facebook:

Still waiting... hungry...tired...grumpy. :(
Then, the chaplain, Sister Elaine, came by. :)

The first comment on my update came from a rabbi and cyclist friend in Toronto:

Hey - I actually knew a wonderful Chaplain named Sister Elaine at MSK when I did an internship in Hospital Chaplaincy many years ago...she had white curly hair. I wonder if that is the same Sister Elaine?! She was AWESOME!!!!!! (This was in 1988-89).

No doubt, it was the same Sister Elaine:

‎@Sharon -- it is totally the same Sister Elaine. She was great!

To which Sharon responded:   

That is awesome! If you see her again, tell her I said "Hello!" I was there for a year my last year of rabbinical school! xo ♥

Although I did not see her again during my stay, I certainly will remember her kindness for a long time to come.

Thanks, Sister Elaine.

So, is this a small Jewish world story?  Discuss.
