Should they be mad at me? or not?

Ok so this week two of my friends all of a sudden stopped talking to me and when i tried to get close to them or ask them somthing they would push me away or ignore me, i know that their listening too. So i decided to call one of my best friends who were friends with them too and i asked her " why is (insert name here) mad at me? My friend knew and told me and it turns out my one friend was mad because she wanted me to print like 23 2-sided copys of somthing and my mom wouldnt letme do it, and the other one is mad at me because she made me a disgusting smoothie thing it was like Milk, icecream, creamcheese, and mints mixed together and i tried it and then i wass like " um its kinda minty...i dont really like it" and now their both spreading rumors about me being a ***** around school...
