Lmaooo yawning too much!
Apparently he looks too disinterested and like he wants to change jobs.
In reality he is just simply tired because he wakes up ridiculously early for work and then goes home to do UNPAID after hours overtime on the work phone, where he deals with super disabled and super old people with dementia calling him at all hours of the day
So now he is self conscious of yawning at work
Nice
