Confront issues directly
Your parents will always be your parents no matter your age and they will always consider you their child.
It might be challenging to get them to recognize your independence when you maintain your own household. But it is even more challenging when you return to your parent’s house for whatever reason.
Reminding yourself that it is only temporary and resolving to avoid conflict by biting your tongue is one way to handle the situation. This could help keep the peace if the tension is only due to the close quarters you now share.
However, it is better to address concerns as they come up instead of avoiding them and letting their summer.
Be clear and specific
Do not avoid or be vague about the situation you are in. Unclear or confusing boundaries allow misinterpretation and worsen the situation.
It is best to be clear and specific about what exactly you need from your parents and tell them the right way. You might need to be more polite and give specific examples. Also, remember to show gratitude.
