Phlegmatic person
These are serious and thorough people. What will be frenzied by the cholera, make the sanguine laugh or cry a melancholic, will not make the slightest impression on phlegmatic. This is due not to his callousness, but with scarce emotionality. However, these are very reliable, reasonable and prudent people. They will not do anything at random. They need to weigh everything thoroughly. His apparent slowness can sometimes even annoy.
