Q. How can I discipline inconsiderate people who do not reply properly to wedding invitations? I am being driven demented by replies on cards from people who have scrawled, for example, what looks like ‘Tom M’ and ‘James P’, which do not correspond to anything on my list. I refused to spoon-feed guests by enclosing a reply card but, even if I had done so, it would not have mitigated the problem of scrawlers and nickname users.
