Yeah I totally agree with Smallfry, be a crew and team member and join in.
Remember the safety aspects. In my opinion your primary role is the safety of the passengers. Know how to carry out an emergency evacuation, where the fire extinguishers and portable oxygen are, how to open the door and emergency exits, etc... Know the flight times and eta local times, ask the pilots for the weather at the destination so you can tell the pax instead of the "hang on I'll just go and check" answer.
All I can tell you about the history of the CFA's on our machine is that they both came from Airlines. I have heard of CFA's getting jobs straight from college because they "looked the part"!!
Best of luck
