I don't really keep it a secret, but I try not to bring it up. It's a little embarrassing to admit I do it six days a week, especially when other people my age go out all the time and drink and spend money on stuff like Coach bags. Admitting that I am always busy with skating or figure skating club stuff and that I put most of my spare money into skating makes me feel like an oddball.
Most of my co-workers know. After I passed my pre-bronze MITF and FS tests, I emailed all the people in my office to tell them. I'd left early to take the test and they all wished me luck and were supportive. Or so I thought. One of my co-workers forwarded my email to someone else and said "Have you ever seen someone so full of herself?" Only, she accidentally included me.
It was awful. I confronted her, we both cried, she apologized and said it was more about her and wishing she was young and living life to the fullest again than me. I forgave her...mostly. She no longer works with me, and we haven't talked in almost a year.
So after that, I've tried to keep tests and competitions on the down low, but people ask me about them anyway.
Most people are very supportive. Most adults I know can barely inch around the rink on skates, so I don't get the "What, no triples?" kinds of comments.
