We have had my fiancé's grandparents up for Xmas. They leave tomorrow and I found out from my parents that they have been discussing my fiancé and I finances behind our backs. My parents help us out with a bit of debt we had at the start of the year however we paid back every month and paid it back quicker than we thought. We borrowed some money from the grandparents last month due to things being tighter than we thought. Are we unreasonable to be pissed off that they are discussing us?
