A poem on my coffee mug says that Gemini friends "tell you that crying crying is good now and then and you come away wiser and older".
Its not aimed at the death of a parent, but I do think its good to release your sadness on occasions like this.
At my dad's funeral, I certainly cracked up inside when I saw hundreds of mourners paying their respects on the roadways to Linthorpe Crem. My dad unfortunately passed away with a not a penny to his name and was a relatively quiet guy in life, with simple interests, but obviously he left a quite big positive impression in people's hearts.
