Marco, it's so hard when we lose one of our parents. My mom passed after a long illness back in '96, but as long as my sisters & I, plus all her friends remember her she did not die. She was an artist, and gave me a lifelong passion for finding beauty wherever I look.
I'm sure that your father gave you similar gifts, and he will live on in your fond memories of interacting with him, in situations both large & small.
In the beginning parents give us life...and then there comes a time where we give life to their memory...
Peace.
