I am not embarassed by my zoo obsession, i'ved lived with it all my life, but it's not my sole interest, apart probably from sport!! I have very little interest in the arts, and do not consider it any more nerdy to go to the zoo(alone or with children) than say a concert, art gallery, museum,castle, walk up a mountain,go fishing or go to a car boot sale! Everyone that knows me knows i regularly go to the zoo, i just don't go on about it to people who aren't interested e.g when in the pub! But at work it makes me useful, like others, as anyone going on holiday with kids will always ask me what i think of the zoos in that area. If they go to a zoo i haven't been to they bring me a guide back, i was very grateful for the berlin one!
