I am an astronomer by trade. I recieved a Msc in Astrophysics and am pursuing my Phd in Astronomy. If I meet someone and I want to talk to them I tell them "I am an Astonomer" and they reply, Oh can you tell me my horoscope (which is ok if they are cute). If I don't want to talk to them I tell them "I am an Astrophysicist". They say I was never any good at maths in school. The conversation ends there.
