Do you discuss your martial arts interest or training with people who are not involved?
Sometimes acquaintances, co-workers and relatives get wind of what you do in the evenings and the inevitable questions are asked. You'll have to field queries on what Dan you are, how many bricks you can smash, what would you do in a real fight, how you'd get beaten up if attacked by a platoon of commandos....
Martial arts, whether you like it or not, are part of the pastimes classed as "weird". Grown adults wearing pyjamas, rolling around on the floor or uttering strange mantras. Yeah, that would count as weird. Then you have public perception based upon movies, cartoons, urban myths and the stories invented by martial artists to make themselves look better.
Some people will be genuinely interested, but in my experience most people just want to sneer and laugh at you when they talk about martial arts.
Keep Calm and Carry On!
