ISFJ: *opening up Christmas presents* You know, everything can be used to kill you. This bow could wrap around your neck and strangle you! This mug could be broken into shards and stab you!
INFJ: Please don’t . . . I just gave you that mug . . .
ISFJ: See this little piece of plastic? I could even PINCH you with it! Or stab your eyes with it.
INTJ: I suppose you could. It’s not the most OPTIMAL way of doing that, but you could.
INFJ: *mildly disturbed* Guys . . . it’s Christmas . . .
ISFJ: Merry Christmas! =)
