My sister gave a cactus as a present for me.
See~It is cute.
There are many feathers on it.
But don't think it is very easy to touch.
It is cute but danger.
Actuality,the shape which the needles on it are like hook.
The needles will hook your skin and you will feel hurt and itch.
You might say why I know that?
Because I have some painful experiences on it.
It hook me twice.
Although sometimes I feel it is danger.
But someone says the cactus can absorb the computer irradiation
So I put it on my lab table.
My sister says she will give another cactus to me.
She thinks this cactus is too danger for me.
I have a great sister,right?
