After I have played outside with my sister and rolled in the dirt, slid down the slide and threw balls at each other, we picked up a lot of dirt and sweat that my sister and I just could not wipe clean. We get in the house and decide who should go to shower first. We go to our rooms and peel off all the sticky and yucky clothes and gather our clean clothes and underwear. My sister goes first. She turns on the faucet and sets the water at a temperature that is not too warm or cool. We both know to step in carefully, get our wash clothes and soap. A fresh shower with shower and water we know will wash away all the grime from our bodies and hair. We made sure we had clean towels to dry off.  Stepping out of the shower and being clean and fresh really feels good after a long day of play.
