My grandma was the type of person who always liked having people around and would cook lunch or dinner for her guests. Now I come around and the best response I get is a grunt and she usually retreats to her room. It’s not just me she does this too now. Mostly females in the family. I keep my horses at their place and so am around a fair bit, my grandpa just had a knee surgery as well so I come to help. Any ideas how to deal with this behaviour?
