Well, the association are dunes:
(Well okay yes, difficult to recognise this hill as a dune - but rest assured, it is one!)
And the association with Egypt, of course the latest news. True, I didn't comment on Tunisia, but this is a blog and not a news show.
I don't know anybody from the latter country, but I do know somebody from Egypt - and if you scroll down my blog you will find that I've actually got three Egyptian readers (I don't know the other two).
So anyway, to all Egyptian and potential Tunisian readers, and this really comes from the heart - I only hope that you will have a smooth transition to a more liberal regime. That is: as smooth as is possible at all, as so far things haven't been too peaceful.
Take care, and don't give up hope!
