… I don’t eat dinuguan (any food with blood in it) if I’m with my Iglesia Ni Cristo friends!
… I don’t order coffee after eating if I’m with my LDS (colloquially known as “Mormons”) friends!
… I don’t greet my friends a happy birthday if they’re members of Jehova’s Witness!
… I don’t ask my Seventh-Day Adventist friends for a game of golf on Saturdays!
… I don’t order food with pork in it if I’m with my Muslim friends!
… I don’t say anything if my friends are doing what the ancient Romans and Greeks were doing, it’s their tradition since birth!
… And I don’t talk anything about religion if I’m with my freethinking friends, we only talk about politics!
Be sensitive with what your friends’ beliefs are if you’re with them… That’s how I define courtesy in today’s society with highly diversified beliefs!
