A sort of silly version of how I understand the functions (which may be way off, assuming the brain actually uses something like these functions.):
Se: there is dark brown, sticky, mud on my shoe
Si: there is some mud on my shoe that is not normally there
Ne: there is some mud on my shoe, that might have come from the ground, the sidewalk, an alien depositing it there, a prank being played....
Ni: there is some mud on my shoe, getting it off could involve either running, dissolving plus rubbing to clear it, maybe some soap...
Te: There is mud on my shoe that must be off NOW!
Ti: there is mud on my shoe that must have come from some outside source.
Fe: there is mud on my shoe, that will offend the people around me, and should be taken off
Fi: there is mud on my shoe, I do not value mud on the shoes, so will remove it. (this one is iffy, I'm not too sure how to connect personal values with this situation.)
