One Track Mind

Some people have an inability to talk about anything apart from what they are interested in. At the moment I've noticed it's dogs. Some people seem completely unhappy if you're talking about another subject. But I'm sorry I cannot have a 2 hour conversation about them. Yes they're cute to look at and great to have a cuddle with but when did it become acceptable for a conversation to be dominated by them. The worst part is when people refer to them as children or liken them to. There is a HUGE difference!
