Am i right or is my sister

So my mom buys alot of mcdonalds for us for 2 days cause she is rarely here so i eat a little to save it then i leave for school my sister than eats some but also lets her friend eats it but i didnt know till later. When im home its all gone then i go pick her up from the bus. I ask her did she come over today cause i told them both not to but she lies and says no. I confront her of it and she starts crying like a little brat and runs home and wakes up my moms friend who lives at our house then she rings the doorbell and wakes him up were moving and were not telling him then her friend tells so there goes that then he screams at me like why the heck did u make her cry and im like i did nothing there very imature and destructive btw then he says just dont talk to me so am i right or is she right?
