Kernel has a great method you can call. "caller". 

Returns an array of the stack that called you. 
So if you want to just see your immediate caller, 
you can do puts "who called me caller=#{caller.first}" 
and it will print the immediate caller. 
If your method is being called from multiple clients this seems useful in debugging..
