I need someone to answer my friend question please?

yesterday was friday and my friend maria and two of my other friends planned to go to maria's dad's restaurant and they invited me and so we went after school and everything was okay and it was fun and we took a lot of pictures.when we got to her house we went directly outside to the pull and there is this section of the pool on top where there is a smaller section letting water go down to the larger section well we started playing on the edges of that section and then my friend told me to push maria into the pull and didn't want to but she said it would be funny and so i told my friend lily to play with maria so that i could trick maria into making her think i was going to push her in and so i did but i guess i let go to soon and she sorta jumped in and then she got mad and took a shower for a long time and her phone got sodden and broke and i felt bad and apologized and so did lily but didn't answer so i called my mom to pick me up around 8 pm that day after i cried and cried she called and told me that everything was fine and that its ok but then her mom called at 10 and she said that she had made maria apologize thankfully its winter break and i dont have to deal with her for 2 weeks but she is always on facebook and oovoo and what can i do and what can ido when i go back to school???
