Caught in the act

The next day was Sunday so we went to church but during service I noticed he wasn't at the seat he took while entering the church I was really worried so I told my parents then we started calling his number but he wasn't answering we then decided to wait after service we will go home he must surely come home after all he will then explain himself. After service we got home my mom went to the kitchen while my dad was in the living room watching TV, so I went to my room then I heard a voice from my parent room so I went to check it out then I saw my brother I was about to call my parents to inform them he was home but he hold my mouth a told me to keep quiet and speak low I was confused was he hiding anything from me so I ask him to tell me what he was doing and why he skipped church he didn't answer at first but I keep asking him even when he was checking my parents things so he finally agreed to tell me but as he was about to say something our parents came into the room and asked us what we were looking for and ask my brother why he left church I brother said he wanted to use the toilet then my parents as him couldn't he use the one in church he gave a excuse that he doesn't use public toilet and they ask again what we were doing in their room then my brother said we were arguing a mistaking entered I knew it was a lie but I played along but my parents bought All my brother's lies like it was the full truth when we left the room I ask my brother to tell me the secret but he said he was keeping it from me for my one safety but I didn't understand and was I in danger.
