It's not a good idea to be someone you're not, especially with new people. You might find that they are fun to be with. They might not find your alter ego so appealing. That's the fact. The reality is everyone wants an easy life, so if that means falsehood and reservations then that's what is going to come out. Only solace you get is knowing that most other people are full of shit too. In the wise words of Dr. House - Everybody lies!
fake people i laugh at: people using different voices to sound nicer, car sales men, fake assholes that try to act rich, people that constantly act like they are to good for everything. i just act normal, calm cool collected, to them and expose their imposter ass attitudes/dispositions/deportment.
