Liars lying

Soo someone in the house moved something (just stupid paper towels) and when my mom was like "who did it?" everyone was like "wasn't me." But she got mad because now that means someone Is lying to her and then she decided everyone in the house is a liar which annoyed me because obviously I did not lie. I think it was my older brother, I don't know if maybe he just forgot or did it on purpose. Also it could've been my other younger brother for some reason. There's no reason to even move the things that was moved, nothing important at all. I first thought it was my older brother because he's proven he does dumb stuff and has also lied straight to my mom's face and we are both aware of this but someone everybody in the house is a liar and not just the one person who's actually lied to you. I suppose it could've been my younger brother but why would he do that I just don't know, he has absolutely no reason to do that. I mean nobody does. Anyway I just didn't like being accused when I'm probably one of the people in the house that hasn't lied to my mom in a very long time so I was offended. It wasn't anything that serious though. Just made me slightly frustrated. 

Still have no idea who did it. 

Also side note, my brother was like "I swear on my daughter's life." And it just annoys me when people swear on other's lives because one, you could be lying. Two you don't think swearing on somebody's life will do anything so it means nothing when you say it. And three, even if you're telling the truth why would you want to even bring someone's life into the conversation. Annoying. I hope nobody has ever sweared on my life, if you swear on my life I'm making you unswear. 

My older brother likes to act like he's so grown and stuff, you're 21 and act like a 16 year old. I sometimes question who's actually the older sibling here. Also I don't like how he was like "I'm a grown man what would you do to me even if I was lying" first of all our mom could probably pick you up and snap you in half if she felt it so could our stepdad or she could just kick you out and she would just not trust you at all and would not take anything you say seriously. Just because you're an adult does not make you untouchable. I'm a pushover though so I couldn't do much..
