By herself

Erica came by herself on this trip. She needed alone time and she got it on this cruise trip.

Erica went back to her room. As she opened the door to her room a thought came into her mind.

She was alone on the trip and felt a little bit daring. She had a thought of skinny dipping but quickly dismissed the thought.

She was alone and nobody on the cruise knew her? She could streak or skinny dip.

She had clothes in her room and could always go back.

After a minute of thinking Erica came to a conclusion.
