first thing is I want to say your question is not stupid at all. not everyone will have an opinion or something to add. that's ok . but it doesn't make your question stupid at all.

I have caught my T in a few lies .it left me wondering and confused about why she needed to lie about it.
once was when I was heading to T I saw her out on a walk heading away from the office . I knew she was going to be late for my session because it was already only one minute till my session . she was 15 min late as she walked through the door .she said she was sorry for the wait but that she got held up in a meeting. don't understand .I would have had more respect if she said I went for a walk to clear my head or something . but the lie didn't hurt anyone in the end so I let it go and no big deal
