that 10-year--old age really is lovely. H left just a week before my birthday; my three were 10 then. We have a family birthday ritual that we do in the morning, it involves all other family members bringing cake, coffee, etc. to the birthday person in bed. All three really stepped up to the bar that year, they weren't even particularly comfortable with boiling water or anything but they did it, found everything themselves, candles included and brought it up for me, singing.
they have done so each year since, and were wonderful on mother's day as well. (not that they aren't otherwise, but you know what I mean....)
