Scratch And Sniff

I have used the 'like' button on facebook
when it seemed fit, never on cheap adverts.
Nor on what seemed suspiciously like fishing sites,
though I took them as part of the nature of the 'net.
A place where nobody could never quite be sure, of anything.

But now I look more carefully and 'like' less,
and prefer to think that the if dogs ran facebook
then the 'like' sign would be a raised dog leg,
a dislike sign would be an icon of a cat
(since that was who the offering was fit for)
and the deepest approval would be shown
by the biggest and the blackest of twitching noses....
