Eh, feeling tired is a generic symptom of many illnesses. Now of course it's possible that these people do tune into different versions of feeling tired beyond the general feeling and can associate it with a cold coming up specifically. I myself can't be bothered to analyse this sort of stuff in such a fine tuned way.
I am so annoyed by people mistyping their HA function as their lead function. Again, I believe this boils down to the "Arrogance of HA".
Like, several LIE guys will want to mistype themselves as SLE. Just because SLE sounds more like something they'd like to be, especially in a society that encourages men to act like SLEs.
E8 LIE guys in particular want to be more like/see themselves to be SLE (it does not help the SLE descriptions are hardcore E8), so they'll see themselves as being strong Se lead while they are obviously Se HA. Honestly, this can seem pathetic to me very quickly.
"I totally use force."
"SLEs are supposed to be the best leaders. (I think I am the best leader.) I must be SLE."
