Your children-are wonderful, aren’t they?
Adult children seem to range from “competent and never call”, to attentive, to “having trouble sitting the right way round on a toilet seat”. Some have already received more money than the other children, there are spendthrifts married to unreliable spouses, drunken womanizing sons etc.
I usually advise against “ruling from the grave” unless there are medical reasons or there is a really serious issue. I feel it is better to spend it before you go (an increasingly popular option) or to divide it between the children equally and let them get on with it.
