I have taken my girl out on occassion for a walk around my apartment complex. Most of the time people don't seem to even notice. Maybe they think it's a necklace? Or maybe they are just to busy with what they are doing or thinking to not notice.
I have had two very interesting conversations with people who did see it. They were very inquisitive and thought it was cool.
I wouldn't take it to work. I'd probably get sent home or fired.
