Very nice. You and your sister Ann (and probably your brothers, though I have not heard them yet) are going to sound great together, with you coming across as the older sister than mostly understands what is going on in the Adult world. (At least in Act 1 - let's see what the play has you do in the future acts!)
Act 1 is missing a line at 4:23 in your file - a joint line with France at the very top of page 14.
At 4:51, I hear "But it's so Aunt Agatha" where the text at the top of page 15 has "But so is Aunt Agatha". We don't worry about being word perfect to the text when we call out "Standard PL" for a dramatic work, but this changes the meaning for a listener and that is important.
The line at 6:30 is actually to be said by Ann - calling out your name so it does look like a line for you, but it is Ann alone. You can cut this out of your file.
Again - very nice.
Thanks, Todd
