I don't care what people think. My business is my business. If they don't like it well that's their problem. I am happy.
Yes I agree with the Original poster in saying that some people look at you sideways when you tell them you keep fish, but I bet that they have some hobby that is a bit different too and they just are too scared to tell anyone else for fear of prejudice. Most who make fun of others are usually insecure themselves.
Life is full of different people, that's what makes us unique.
