Yes this! My parents tend to email me and my sister moderately detailed trip itineraries, -- dates, flights, and motels -- and in return we generally forward them our flight schedules. But this is strictly voluntary on both sides.

If my mom pushes for more detailed information, like what time I plan to leave for the airport, am I sure I have enough money to pay for parking, what will I do if there's a delay, etcetera, that's where I say "I have it handled" and change the subject -- because that's her anxiety talking and honestly it's none of her business. To her credit, she self-corrects when reminded.
