No one can replace the love a father gives, or his support or guidance. I can't imagine the heaviness in your hearts. Death has taken away a man you adored, but it can not take away those precious memories you have of the times you shared together. Allow the tears that flow to wash away your sadness. Take the time to grieve, in doing so reflect on the good times you had in the presence of you father. He is still a guiding light in your lives.
