When I read your mother's and your bad habit I remembered my grandmother also had this habit of talking with the TV and when we asked or said something to her to get her attention she got annoyed. Unfortunately we lost her, but her memories stays with us. Thank you for reminding it.
My bad habit is sometimes I raise my voice unintentionally when I talk about something I am excited about and my wife warns me always. I am trying to avoid it, but as the saying goes "Once a priest, always a priest":-)
I’m happy I could bring back some good memories of your grandmother😊Hahaha that’s a good saying😁absolutely true))
