DEAR ABBY: Could you please tell me what's proper in a situation like this? My husband and I are always invited to his family's holiday celebrations. When we accept, the invitation is also extended to my mother and sister. If my husband and I are unable to attend, should my mother and sister still go or consider their invitation canceled? -- JAN IN SAN CLEMENTE, CALIF.
DEAR JAN: If the invitations that were extended were accepted by your mother and sister, and they are expected, they should attend.
