tell me your best advice, I'm giving a presentation

[OrcishOrchids]

hey everybody! somehow I got labeled as the "orchid person" in my circle of acquaintance, and now I'm the opening act for a master gardener lecturing at my church. I've been asked to give a 15min talk about growing orchids to a group of ladies age 20-70 with little to no experience with plants. it's unpaid volunteer time, so I won't be compensated for anyone else's experience, I just want to set people on the right path if I can.

what do you think would be the most important things to get across? I was thinking of debunking the myth that they are fragile and impossible to grow, and taking a variety of media samples and plants to display, but I'm not sure how to prioritize everything else. I've printed out basic care sheets from the AOS for phals and cattleyas (what is mostly available here)
my husband will be handling pests (an entomologist) and the master gardener will be handling all the other plants.
