You see, I don't think any of them are insane. It's far, far simpler than that - they are all geeks with regard to their pet subjects and as such are subject to the geek laws of sanity which are completely different to normal people laws of sanity.

By the standards of my friends (including my husband), these men are completely sane. It's everyone else who is mad.

It's always pleasant living in the asylum, I say.
