Such a contradicting tritype. The energies/drives go into completely different directions.

7 is like: "Heyyyyyyy let's have fun and escape shit! Tomorrow is a good day, fellas! Partey <3 Also I have the best ideas ever."
8 is like: "Greetings, it's your boss, I run this. Give me authority and more of everything. If you hurt weak people I'll end you, all right."
3 is like "Hello I am a successful robot who feels empty and wants to look awesome in your eyes. Good, time to work harder then"
