Southeast Leatherfest is a big grown-up party where people who like to wear leather clothes and have different types of relationships get together to learn and have fun. Kind of like when you go to a big party and play with your friends, but this party is just for adults and they teach each other things like how to be safe and respectful when they're playing together.
At Southeast Leatherfest, people come from all over to learn about things like bondage (which is when you tie someone up with ropes), dominance and submission (which is when one person takes charge and the other person follows), and other kinds of things that grown-ups might enjoy doing together. There are also people who might be there just to hang out, have a few drinks and dance to music.
Just like when you go to a birthday party, everyone has to follow some rules to make sure people are safe and happy. That means everyone has to respect each other's boundaries and ask before doing anything. Some people might use special words like "sir" or "ma'am" to show respect. There are even people there who are trained to help if someone feels uncomfortable or needs help with anything.
Overall, Southeast Leatherfest is just a fun party where adults go to hang out and learn new things about themselves and others. But just like with any party, everyone has to be kind and respectful to each other.
