Am maybe a little paranoid but wasn't keen this evening on questions asked by cab driver. I'm quite chatty so did the usual "have you been on long, will it be a long shift etc". However he asked me... "what does your hisbiand do", does he work long hours, do you have a dog, what type of dog is that, is that an aggressive dog and is it like a guard dog, do you use your dog as a guard dog" ... am I being a bit paranoid but those questions seemed a bit off
