Rude???? That's obnoxious ! Who the f*** does she think she is? You are not her live in nanny you are a care provider and I'm pretty sure you actually have a life. If one of my parents never showed up when they were supposed to with out letting me know I would snap. One of my parents actually texted my and said "oh btw I'm staying late I'll be there at xxxx time". And even though it was within my operating hours I told her she had to ask and not just assume as I have to stay within my numbers and I have afterschool kids. Therefore you ask if it's ok as I am not at anybodys beck and call
