Oversharer alert! As outspoken Jupiter locks horns with expressive Mercury today, you may be tempted to let it all hang out with someone you’re still getting to know. Unless you want to wake up tomorrow with a giant vulnerability hangover, don’t be such an open book. It’s okay to share a few pages from your personal history. But when you’re done with one story, wait and let the other person reciprocate. That way, you won’t flood them with TMI and your connection can stay on an even keel. Boundaries have a purpose, even in the most intimate relationships.
