Where can I go home?

Today, it was a lady asking me where can she wait for (to go home)?
Me: Not today.
She: A lady said it's today.
Me: ... (Not supposed to tell her anything cause I don't really know much about her.)
But, she was really wanting to sit somewhere to get home.
I brought her to another lounge space.
She sat there and I told her that I would find the answer for her.
I went away and do my works.
Few minutes later, she walked towards me and asked me the same questions again.
I was in my wit's end.
When she saw another lady (a career), she asked, "sister, where can I wait to go home"
The lady said, "not today, it will be tomorrow." .... "at 10 o'clock."
Everyone knows the career was telling a lie, except her.
She was quite disappointed. And, became quite aggressive at times.
She was really looking forward to go home, I supposed.
But, definitely not gonna happen at this stage.
Pity her. Because everyone is lying on her.
Including me. Bitch telling a lie on a very ill dementia lady.
How bad am I? Very bad.
I feel bad too. But, you not gonna tell her the truth, aren't you?

She is a very lovely lady, gently kissed on my hands after I've carried her to a couch. She even asked me to sit down with her to wait for the bus (the bus to take her home). But, where is the bus? Or will the bus be arrived in the lounge? This is ridiculous, isn't it? But, dementia people don't think it is. I'm quite aware of their sundowning symptoms. When it is the sundown, they think they should be home, not here. The space locked with security doors, only the staffs can access the code to go through.

Sad stories make people sick.
Don't you think so?
