This is not a good atmosphere for a visit. Perhaps you really can't get your house in perfect order and gourmet meals prepared but at least take special care with the space guests will use so that they feel expected and welcomed. Grandparents, if you are doing the visiting, try to be good guests. Don't be hypercritical if things aren't exactly the way you hoped they would be. Plan the details of your arrival and you stay so that they cause minimal disruption to the household.
Grandparents are more likely to be the visitors for several reasons.
It's expensive for a whole family to travel. Many grandparents have moved from larger homes to small apartments, so there is often more room for all at the grandchild's home. Many families have children in school and can only travel at certain times of the year while grandparents have flexible schedules and can travel when they like. Grandparents, please think before you speak. Don't remind your grown children to wear sweaters or carry umbrellas.
