On a warm summer day last week, my dad took my sister and I to the community pool. After a few hours, we were ready to leave so I grabbed my sister's bag and changed into the clothes that she had packed for me. When I left the changing room, a girl started yelling at me for "stealing" her clothes. Everyone at the pool, even the cute lifeguard, watched me turn bright red before I ran back inside. It turns out that my sister had her bag the whole time and I had taken someone else's by mistake. Now, I bring my own bag.
