Follow your curiosity even if someone close thinks you're wasting your time. Ask yourself if they actually dismissed this interest, or if you're borrowing a reaction from an old conversation - or another person entirely? But tell them why something excites you and give them a fair chance to respond. If they don't share your enthusiasm, then try to work around relationship limits. But if what excites you does zilch for their mojo, that should not be your problem.

Give that trip, course or abandoned plan another look. A decision made to pause or cancel it in the past may not be appropriate now. Even if an arrangement looks transparent and straightforward, don't let assumptions creep in. Agreeing on everything upfront or getting something in writing is wise. This might resolve a home or family issue as well. Widen communication lines where you think discussion isn't needed or you've already been around a certain topic umpteen times.
