You

when
it or they have done something that you find
extremely annoying or
surprising: And
you say she's opening
your letters now?
Oh, that really takes
the
biscuit!
Did you know that the golden wattle, a type of acacia tree, is a symbol, an emblem of Australia? I didn't!!! I only learnt it when I read that the newborn princess Charlotte Elisabeth Diana has received "a cot blanket made of merino wool from Tasmania with embroidered wattle" as a gift from the Australian people. This year we are learning a lot of things about Australia's fauna and flora!!! Bilbies, wombats, echidnas, pigmy possums, etc.
