"When I was 13yo, parents were out having a dinner date. At the time my family lived [in a ] quiet place, so my parents didn't think much of leaving me alone with my 9yo little brother for an hour or two. I was putting him to bed when I herd a knock on the door. This knock was loud and he banged several times before stopping for a moment. I heard glass shatter, I immediately grabbed my 22 long rifle my parents got for me, and hid in my little brother's room behind his bed with rifle mounted at the door..told him to hide under the bed. [...]
"I remember thinking to myself to protect my little brother at any cost. I heard noises [first] in the kitchen, then the living room, then my room, then finally the hallway to my little brother's room. As the door opened I saw an unfamiliar guy, he quickly seen me then rushed me. I fired all the rounds in my rifle. I just remember him dropping on the floor with a loud thud, my brother crying.
"I called my parents after which they called the police. After talking with my parents, they told me the police said that the guy was our next-door neighbor and a registered sex offender most likely was staking out the house and he noticed we were home but our parents weren't." — lol_Roxas
Apparently, from then on their parents took them with them if they ever went out for dinner.
