['My uncle tragically passed away in a car accident, leaving behind his wife and son. I desperately wanted to help them in their time of need, even if it was simply cleaning the house. They are the sweetest family.']
That is really good and will be helpful.  I lost my wife to cancer years ago and people helping was great.
When a family member passed away, my heart ached for his wife. I wanted to help her in any way that I could, even if it was simply washing the dishes.
