I've observed that older you get the more your "filters" are suppressed and eventually turn off.
I've had to tell my 84 year old mother that she should think twice before saying something. She seems to be pissing off people around her with her blunt talk.
She's made some very blunt comments about my niece and daughter in front of them. It just tell them "Grandma has no filters and she means no harm".
I find i'm less tolerant of a$$holes and let them know it. I have more years behind then ahead so there's no reason to ***** foot around when it comes to these people.
