Please tell me.......

....is this a Caper, a Spurge or an Euphorbia?  I have a feeling it might be known as all three.  The whole plant is shown in my extra.

Today, yes, well, enough said!  As was suggested to me this morning "Try to think positively and put nasty thoughts in a box in your mind and keep it closed!"  


Probably a good idea but hard nonetheless.
