jonas*: "filipa, whose turn is it to babysit tomorrow? momi's or grosi's?"
filipa: "well, when i talked to grosi on the phone yesterday, she said that we will see each other in two days. if today is the first day, then tomorrow will be the second one — so it must be grosi's!"
* just to set the record straight: filipa doesn't actually understand nor speak english ;-)
