Allie goes through stages where she'll buy lunch a lot, then she'll bring it for a while again. This note was written during one of her buying stages where she had bought a lot in previous days:
Not trying to make her feel guilty for buying or anything, but she is missing out on the notes her sister is getting. As the title says, if only I knew which lunch tray she'd be using...I could come to school and tape the note to the bottom or something! That's not over the top is it?
