Bridge Between 2 Worlds

Have you ever had trouble explaining certain religious ideas/concepts/beliefs to people who don't share the same religion/belief system?
The other day I was trying to explain the concept of the evil eye to my mum and sister, and as I heard myself talk I wondered whether it even made sense to me. I strongly believe in the evil eye but find it so hard to explain to non-Muslims. It just ends up sounding so superstitious and backwards.
Has anyone else had an experience like this?

On a side note, I'm finally done moving so inshallah I'll have more time to blog and comment now!
