LStew, I am so sorry about the loss of your precious son. Was he sick or did he die suddenly (if you feel like talking about it; if not, I understand). I can't fathom that kind of pain. Your UPS driver got to see a side of a grieving mother that I'm sure he's never forgotten--which is good, not bad. We sometimes just don't know what to do with the raw pain of separation from one we loved with every fiber of our being. I'm also sorry about your dad. I absolutely dread the day I also lose my dad. Not a day goes by I don't give it a thought , so I don't take him for granted.
Your sister's kids are really cute and they must bring you special joy.
