Inspired by another thread(s):

Has anyone ever accidentally overheard, eavesdropped or snooped conversation of in-laws ? What did you discover ? I am not talking about conversations which they want you to hear, but rather their conversations about you and your family of origin which they didn't want or expect you to hear.

I would be really interested in knowing what they say about me and my family as I have never understood why they behave the way they do. Never eavesdropped nor accidentally overheard.
