While it is tempting to lock yourselves away, stepping out for fresh air keeps the vibe from getting stale.

Buy sheet masks, scented massage oils, and bath bombs. Put on a lo-fi playlist and give each other relaxing massages.

Do a deep clean of the house the night before the parents return. Wash the sheets, take out the trash, and put everything back where it belongs.

If staying at home feels too quiet, use this time to paint the town red without worrying about a curfew.

It is still her parents' house. Keep it clean and do not break anything.
