its not so much as you are ignoring her, its you are too busy (at least you will be, won't you!!!!), and it is really not that urgent to get back to her is it? She never actually asked you a question, only made a statement, so IMO it doesn't require any attention. Like my W just recently got TM service on her new phone account. I sent her a text (I shouldn't have but...) to tell her what mail she got today, and to see if it worked from my phone (I don't have texting, I use Yahoo messenger to do my texting). She replied about 40 minutes later, "yes it works". I have no need to reply to that. Just because they text us back, doesn't mean we have to jump and text them.
