Should I?

So i talked to her Friday she told me to create a snapchat account and i didnt do it until today would it be rude to ask for her snap but even worse shes not even suppused to have it so i have to be careful thankfully im a very good whispering. Bonus Weird thing Friday she kept whispering to her brother about stuff that they thin i shouldn't hear even though shes 14 her brother is 13 and im 15 each time i want to say something but thankfully doesnt get the best of me.
