A Puddle Duck to me is someone who is concentrating on something so hard that reality begins to fade. The world around you may be hectic or crazy, yet you are lost in your own world.
When I play games, the game becomes my reality. Even in the real world, I see elements that for a second, I think need to be picked up or activated.
Being a Puddle Duck is a great complement to me. Please don’t be offended when I call you a Puddle Duck.
