If this is a comfort for you: it has nothing to do with the PC.

I have a fishtank and am specialised on certain breeds - I remember a visitor (he had to repair something in my flat) standing in front of my tank - and we had a long chat. His girlfriend hated his fishtank - and he couldn't believe that females not only have one as well but are full of knowledge, interest and love for these animals.

It's a prob if both don't share at least ONE passion. My best friend and her new husband are both fish lovers - when they moved together, they joined them. This flat has 3 tanks now - and even if they quarrel: peace is there if they take care of the fish, exchange knowledge and share the same interest.
