my sister actually paid my back on time last week well , that 's good . did she borrow money from you ? she always does and never pays it back on time . but this time she did perhaps she 's turned over a new leaf . it 's very good of you to lend her money , even if she is your sister . i hope so it 's surprising how people suddenly wake up and realize that perhaps they have n't been acting as perhaps they should have .
The sister's uncharacteristic behavior of borrowing money responsibly caused surprise.
