I think that's a good way to be! I haven't had to attend that many funerals, but I know I felt differently at my great-grandmothers' funerals - especially the one I'd actually known - than at my uncle's, because they'd had good long lives and he hadn't.
I was too young when my brother died to know anything. In fact I've recently begun feeling actual loss when thinking about him. One of the cds I was given for Christmas has a song that could be about him, from the heart defect to the number of days he lived. I can't stop listening to that song. I hear about my little brothers and think "Sam would have been doing such-and-such" and feeling cheated that I didn't really get to know him. Is that weird, to feel almost fresh loss now - 13 years later?
Not at all, Sam. You love life, and you wish he could have had what you have.
