I'm glad you're entering. At our age/stage competitions are really (imo) something very personal. It's not about the podium or final results, but really about our own goals and motivations. The only reason I can think of for you not to do it, would be because of the potential stress closer in resulting from the time you'd need to be off ice. It should be fun and not stressful.....well, not more than a reasonable amount of stress, anyway. It being for you to define "reasonable". So other than for curiousity and/or a chuckle, what that other lady has to say is really irrelevant.
Good luck!!!!
