Sad

She interrupts others' conversations with topics out of nowhere.
She brings up a totally different topic when you are speaking to her as if she was never really listening to you in the first place.

It seems like at times, she is in another world.

Then I watch her when she is not a part of what is going on - when she is not a major part of what is going on - and I see that she wants desperately to be a part of this world. She wants to be someone's whole world.

How sad to watch someone who is so sad.
