An appeal to inventors

I need a new invention 
and I'm not clever enough myself. 

See, I sometimes need intervention. 
Need to leave some things on the virtual shelf . 

A breathalyser for computers . 

An algorithm that just says "Duh".

Something , please something 
to stop me from buying STUPID STUFF! 

I do not remember buying the book, 
that you see in the photo above. 
Another bizarre surprise arriving,
in the haze of a hangovers dust . 

I think I know why I bought it. 
An old poem called Dandelion Clock . 

I know that I really don't want it  

Sparrowsong, would you like a book?
