Yes. It has nothing to do with being introvert or extrovert. Or having more things or less.

You noticed it very soon. You were smart from the very beginning.
I had another picture of her and her situation. I didn’t notice it. Although, she put a great effort into showing a happy-lucky face.

Lately, I have the impression she lacks of inner life. Empty.
If I pay her the attention (I must say I’m the one who lives closer to her)…if I call the attention about something. For example, the fact that she engaged so much with his partner that she forgot about her granddaughters, she takes note and try to worry more about them.
Maybe she sees herself old and wants to eat her life by bites. I meant she is in a hurry to live life at its full.
(I don’t know if I’m expressing myself fine now)
I don’t blame her but this is not contradictory with forgetting about their close family or to talk bad about us and having always a but.
She can’t complain about us. Especially about my sister or my brother. I have my temper and I’m the older so I speak to her very straight.

However a good point is that as soon as she knew my doggie Miky passed away, she thought about me and come to visit me and we talk now every day.

Maybe, I’m being too hard with her. All I can say is that we all three, my sister, brother and myself noted the same about her.
