Lost a mentor, teacher and friend...
Pat, so sorry to hear about your dad.
But cherish the many years you had with him. Keep the memories close to your heart and he'll always be with you.
I lost my dad when I was only 7 years old. I have memories but they're faint. But even with the faint memories I still cherish them - and always wonder how my life may have been different if he hadn't passed so soon.
