We do google at dinner a lot, and often to prove each other wrong, but not to put each other down--that's a big difference, and I'm glad that HPF can see what's being modelled and can reject it. That's something to be positive about right there. Good raising!
Friends used to get anxious about how much my family talks over each other, but I think it explains too much about my style of, ah, discourse, and once I realised we do it (and have to--I've tried not, and you just don't get to say anything) I had something to struggle against doing with other people (and especially at work). We are allowed to do a "No, seriously, I want the floor for five minutes, everyone else shut up until I'm done, okay?" from time to time.
