I hate to burst your bubble
When you go into your dance bubble (really, when are you out of it?), remember that your family doesn’t necessarily exist in there with you. Your parents are almost certainly a tremendous support, without which you likely could not do what you do. And your siblings are proud of and inspired by you… even if they don’t show it. But, ultimately, it is your commitment. Don’t expect them to always drop everything to accommodate your dance needs. After all, they probably have their own bubbles.
