And let me start by apologising for using such a wanky phrase but it does work well for this particular thread ;)
For me, it's dog threads. I don't have a dog, no real strong feelings on them and definitely no plans to get one, but I find the threads fascinating (and lets face it there are a lot of them at the moment).
Other ones are inheritance ones - I'm not in line for any inheritance and not even sure what probate is but love these threads.
Anyone else do this for threads that have no real relevance to them?
