What a dainty tea cup
--- Is malnourished / skinny
It is filled with pure white cream
--- Colour ref
So it covers the hot tea below
--- Caneo is Akhal Teke x TB, both 'hot' breeds.
I am sure that it is sweet enough to hide the blades lurking in its depths.
--- Has a small horn
Maybe that is why it was a lonely cup on the table top
-- Described as detached.
