(Not so) hypothetical scenario:
Your T changes your session time to as early as possible for one week in a way you correctly deduce/confirm means s/he is coming in only for you that day, which you know from years of working together means s/he has other important plans that day and may even be traveling, or else s/he'd be seeing more clients or willing to meet later. This scenario, your T lives 1.5-2 hours away from his/her office, so this either means s/he is making an extra three hour trip for just you or else his/her signifcsnt other is waiting around for a couple hours for your session to end if they're traveling elsewhere. You know all this is at least possible/likely, because such scenarios have happened in the recent past when a session has had to be canceled due to T traveling. You will really struggle without this session (also evidenced by a recent skipped session).
