I don't think I'll spend time trying to figure Bukalov's correct typing. I'm simply saying it's not as simple as you previously said how someone being shy can only be an introvert. There are more factors affecting social or other (e.g. sensory) sensitiveness than that.
Lol> Maybe you wake up tomorrow and start typing as IEI.
Sometimes, when the ones who thinks own type as IEI saw my examples they said like "ah. Sol again types any pretty and stupid looking chick as IEI"
