Something to consider. I have a diagnosed mild cognitive impairment. There are people I have literally seen and worked with on a daily basis for over 3 yrs that I suddenly cannot remember their name. What you described about your T looking at you for a moment like they were trying to figure out who you were hit me because I could immediately see myself in front of someone I absolutely know and just can't remember their name. There may be a very good reason this happens that has nothing to do with you at all.
