I also didn't quite understand the family comment either. Whose family are you talking about?
When you are born, you have your mom (and possibly Dad) around you. But as you grow older, Mom and Dad will pass away and you'll thus be alone. Unless you have kids, you'll die alone.
Even if you do have kids, life happens. I know plenty of people who don't talk to their kids or they hate their mom or dad and there is no relation. Thus some people have died alone.
I think some people have this fantasy, that they are on their death bed and there is 3 generations weeping around them.
Sorry, but is this even true any more? Quite honestly for me. I'm quite happy to leave as unnoticed.
Oh and another thing. Friends. Unless you make seriously good friends and not those on facebook or acquaintances. They may be around you a long time. But I have rarely met someone in their 50s/60s that still knows their childhood friends.
So strike that one off the list. I think a life well-meant is what you did with it. Rather than who is in it.
