Saturday my sister-in-law left a phone message saying her mother was upset and crying (and could we go visit her). They had spoken on the phone and my sil corrected my mother-in-law's confusion about a family member coming to visit her that day. The family member had visited the previous weekend. My sil said in her phone message that she "had to burst her bubble", telling her mother the relative wasn't coming to visit. My mother-in-law was disappointed that she wouldn't have the expected visitors and upset about her confusion. Without correction she would have been disappointed when her expected guests didn't arrive or she may have eventually forgotten she expected visitors. Wouldn't it have been kinder to not correct? Any suggestions on resources on communicating with mildly confused elders?
