I am sorry for your loss and I apologize for not seeing your post sooner to express my condolences.
Although your Dad is now gone, no one can take away your memories. The nice thing about memories is that they can be with you in any circumstance and any time. I lost my grandmother this past summer and take solace from fond memories. Her attitude and 'people skills' have always been an inspiration to me and I try to incorporate these atributes into my life.
Your Dad also helped shape your personality and outlook on life. Take a look in the mirror and you will see his influence in your life. I wish you Godspeed and comfort in the trying days ahead.
