Tvarye tushte aham tushtah, kupite kupitastvaham | tvattah priyataro nasti mamanyo dvijpungva || (From Varah Purana)
Says Lord Shiv to Nandi : Satisfying you will satisfy me, distressing you will anger. There will be none more dear to me than you.
It is said that when you whisper something in the ear of Nandi, it reaches Lord Shiv straight.
