A day out to the beach

You ignore the thoughts rising up and quickly finish your shower, as you do you can hear your sister walking around the house. Clearly getting ready.

"Hey sis? That you?" You call out, drying off your hair.

"Yeah! Did you use all of the hot water?" She calls back.

"No I only took a quick one!" You shout back as you walk into your room and to your closet to find some clothes.

Do you :

Put on a pair of jeans and a T-shirt

Put on just your underwear

Nothing at all
