I am a human, because I belong to the species Homo sapiens.
I'm a man, not a woman :-)
I feel like a widower because my wife has left me.
I am a father, because I have got two sons.
I am an earthman because I live on a beautiful planet.
I am an European because I live in Europe.
I am a Pole, because I was born in Poland.
Who are you?!
