Anal people is funny. Don't be anal.
Working in strangers houses all day, you have to find a way to break the ice to find something to talk about besides weather and work. Animals! Lots of people have animals. I find it immaturely entertaining to make up names and call em by the new name the whole time I'm there. So you may have a big sheppard who is Sparkles until I leave, or Paco the cat.
So many of them tell me That's not his name. I'll tell cats to go get their ball, usually get informed cats don't do tricks. Had a guy showing me his horses, I told one to sit and he looked at me like something stupid was said. Told him his horse wasn't too smart.
Random tip, sometimes barking at a barking dog will shut him up.
