Well, yes, they probably are exactly what you called them. Sounds like a good idea to just give them some space, until they make a kind move. If they don't, so much the better. I know that your Mom likes being with their children, but perhaps other family members have children she could share. It would seem to be better that the type of argument you describe. Can you and your Mom leave cousin and his whatever alone, at least until they recover their senses? billieJ
