Tips for teaching my Sire about modern things?

Good evening, as a post title indicates, I've recently given my sire some rather uncomfortable moments talking to him about things like PayPal, drones, fishing, Make the Exorcist Fall in Love (I'm such a fan that I even made two ghouls modified in the likeness of the main characters), etc. They are a Tzimisce of (according to them) about 641 years old, and have been quite a bit more hermit than the average clan member, worse is that they seem to have animosity towards the Toreador, so turning to them is not an option in this case. I need help with this particularly as we intend to start an online sales service for modified Ghouls with viscissitutde, so reporting things like this is important, thank you very much in advance.
