She’s 78 but she didn’t represent that age whatsoever.
I can’t tell if she has low self-esteem. She never showed it. On the contrary.

I think she’s trying to look for excuses to counteract our complains about how she’s behaving with her son, and two daughters (me included) since my dad passed away.
With me even sooner.

She was always pretty superficial and selfish but I didn’t notice it until 20 years ago. She knows very well how to give another face but as long as someone of us is not present, she criticises us. Most of the times her criticises show very low capacity to understand the other person.
All she does is the right and the others are wrong.
There are some occasions when she couldn’t control her real self and I caught it up.
I talked with her about all these issues directly and several times. Her response is always that she didn’t realised.

Actually, after months of no communication with her, I was the one who phoned her to tell her about the loss of our doggie Miky. The reason why I phoned her is because she saw on Instagram a video of my deae Miky that my partner made about him. So, my partner told me that she was going to visit me. And I phoned her with the hope that she didn’t come home. But, she insisted to come later. So I failed in my try.
