Why Do Inflation and Interest Rates Fight Like an Old Married Couple?

Imagine your piggy bank has a special friend called the central bank. When prices go up (that’s inflation), the central bank gets worried and tells banks to charge more for loans, that's interest rates. It's like saying, 'If things are too expensive, people should save more money instead of spending it all.' So inflation and interest rates fight because they're trying to keep your piggy bank happy.
