Have you tried talking to your aunt directly about your work schedule? Putting a note on the door like Seth did can work, but with family it might feel a bit cold. A quick, honest chat is often kinder in the long run. You could tell her you get really focused during certain hours and would love to see her if she checks in first. It sets a clear line without making her feel unwelcome. Letting the frustration build is worse than one slightly awkward conversation.
