Spooky Spike

I phoned my mum last Wednesday while out for a walk. She said something so annoying I argued and shouted down the phone. When I got off the phone Spike had disappeared, I called him and he had sat down back down the track. He was a bit spooked for the whole walk, but ok everywhere else. Problem is he is scared of our walk now, and sits or lies down rather than running about fetching his ball like he normally does. I have just realised that I am getting frustrated with him about it, which is making it worse. I'm going to have to be patient. Oh, and he does it to my other half too, she even reckons he looked at the ball wanger a bit warily.
