Karmic coincidences..?

My sister and I have never gotton along.. we are 3 years apart and our personalities are eons apart.  She is now going through a very difficult divorce.. similar to the one I went through 13 years ago.  So we have been talking a little by phone (we live on opposite ends of the country).

So, a little background here.. when i was divorcing, i was in serious financial straits.. and the pressure can make you go a little nutty.  At one point my car was in the shop, and the mechanic called me to tell me it was either Problem A (which would take about 50 dollars to fix) or Problem B (which would take about 500 dollars to fix).  I got off the phone and the first thought that went through my mind was “gee if it is B I'm going to have to kill myself, I don't have enough money to continue.”  

As sis was telling me her situations, for example, her house is in foreclosure, i was reminded of how crazy my thought processes were.  So afterwards I mailed her a  check and told her it was a little bit of money to make sure if she encountered Problem B, she would have an alternative to ending it all (we both share a love of dark humor).   I had no idea how much to send, i just wrote down an amount and sent it.. no thought involved.

The next weekend she called and told me that as she was pulling her resources together, it turned out the amount she needed to get the house out of foreclosure was the amount of my check.  And she was able to move forward with paying off what she owed.

I know how christianity would explain that.. I am curious how buddhists would explain it.  My teacher has told me i must have tuned into karmic intuition.. and my connection to my sister is much stronger than i had thought.

if nothing else, it's a special story we now share.
