when we've done something to upset her.
She will last a week or so without speaking to her siblings sometimes... this upsets the younger one, not so much the older. Most of the time I try to ignore it and understand what she's feeling, or I try to explain to her that it's ok to feel angry but she must also forgive.. blah blah
Then sometimes I just lose the plot and threaten to cancel her summer school trip... all very stupid I know... but my reserves of patience are very low these days........ scream icon!!!
